Early life
Christina María Aguilera was born on December 18, 1980, in New York City, New York, to Shelly Loraine (née Fidler) and Fausto Wagner Xavier Aguilera. Her father is an Ecuadorian emigrant from Guayaquil while her mother has German, Irish, Welsh, and Dutch ancestry. Fausto Aguilera was an United States Army sergeant, and Shelly Loraine was a violinist member of the American Youth Symphony before becoming a Spanish translator. Due Fausto's military service, Aguilera family was moving frequently, living in New Jersey and Texas. In 1983, they moved to Japan and lived in Sagamihara for at least two years. The family returned to U.S and ultimately settled in Pennsylvania, welcoming her younger sister, Rachel, in 1986. Aguilera has been spoke out about her father's physically and emotionally abusive behavior. She eventually used music to escape her turbulent household. In 1987, Shelly filed divorce to Fausto and moved with children to her mother's home in Rochester, a suburg of Pittsburgh. She later remarried to James Kearns with whom she had a son named Michael. Following decades of estrangement, Aguilera expressed interest in reconciling with her father in 2012.

During childhood, Aguilera explored her grandmother's personal records—which featured mostly soul and blues singers—whose increased her interest in music. She also began to practice singing and competing in talent contests. Followed numerous contests, she earned reputation in the neighborhood as the "little girl with a big voice" and received attention on local television and radio programs. In 1990, she performed the popular song "A Sunday Kind of Love" on the reality competition show Star Search, but was eliminated during the semi-final round. Aguilera eventually was invited to sing "The Star-Spangled Banner" before Pittsburgh Penguins hockey, Pittsburgh Steelers football, and Pittsburgh Pirates baseball games, as well during the 1992 Stanley Cup Finals. During her youth in Pittsburgh metropolitan area, she attended North Allegheny Intermediate High School before leaving there to be homeschooled to avoid bullying she has experienced in the institution.

In 1991, Aguilera auditioned for a position on The All-New Mickey Mouse Club (MMC), aired on the Disney Channel. She ran against 400 candidates and despite making the shortlist, she was not accepted due she did not meet the minimum age requirement. Aguilera received a call from one of the show's producers asking if she was still interested in becoming a "Mouseketeer" in 1992. She returned to competing against 15,000 candidates and was selected to join the variety program the following year. Her fellow cast members included Ryan Gosling, Keri Russell, Britney Spears, and Justin Timberlake. During the show recordings—which included Aguilera performing musical numbers and comedy sketches—she moved with her family to Orlando, Florida. In 1994, it was reported the series would not return for a new season.

Aiming to beginning a music career, Aguilera moved to Japan in 1997. She was selected to record a duet with Japanese singer Keizo Nakanishi, with whom she performed in concert shows around the country. Their song, "All I Wanna Do", was released as a promotional single and failed to reach commercial success. In June 1997, Aguilera went on to Romania to represent the United States in a singers contest during the Golden Stag Festival, but she failed to win over the audience. Seeking for a recording contract, Aguilera recorded numerous demo tapes directed to record labels, including Walt Disney Records, for which she send a cover version of "Run to You" by Whitney Houston. She eventually was given the opportunity to record "Reflection", theme from animated film Mulan (1998), which charted on the Billboard Adult Contemporary chart at number 15.

1999–2001: Breakthrough with debut album
Following the attention received with "Reflection", Ron Fair—A&R executive from RCA Records—offered to Aguilera a deal with the label. In late 1998, she started recording her debut studio album which reportedly had invested $1 million on writers, producers and voice lessons. Although Aguilera's desire to create a material directly inspired by R&B, the label opted for a teen pop production due the genre's high financial return in the late 1990s. Her self-titled debut album, Christina Aguilera, was released in August 1999, and debuted at number one on the Billboard 200. It catapulted Aguilera's popularity globally and sold over ten million copies in its first year of release. It was later certified eight times platinum by Recording Industry Association of America (RIAA), and sold over 17 million copies worldwide.

"Genie in a Bottle" served as the album's lead single, and topped the Billboard Hot 100 for five consecutive weeks. It also rise Aguilera's popularity worldwide, leading charts in over 20 countries. The single attracted the attention of conservative people including celebrities such as Debbie Gibson that spoke out against its lyrical content, and was eventually considered "too provocative" to be sung by a teen idol. Due to the criticism, Radio Disney replaced the original version with a censored one. Other of the album's singles, "What a Girl Wants" and "Come On Over Baby (All I Want Is You)", also topped the Hot 100 chart, while "I Turn to You" reached number three there. At the 42nd Annual Grammy Awards, Aguilera won the Best New Artist, which received wide media coverage. Time credited the award for "[helping] certify her credentials as a real singer". In mid 2000, she embarked on Christina Aguilera in Concert—which visited North America, Latin America, Europe, and Japan.

Aguilera's success continued to rise with the release of her second studio album, Mi Reflejo, in September 2000. It features Spanish-language songs and was produced as a Latin pop material. The album topped both the Billboard Top Latin Albums and Latin Pop Albums for nineteen consecutive weeks and later was certified six times Latin platinum by the RIAA.

Aguilera's commercial success saw her being named the 2000 Top Female Pop Act by Billboard. The same year, she filed a fiduciary duty against manager Steve Kurtz for "improper, undue, and inappropriate influence over her professional activities". She eventually hired Irving Azoff to manage her career, aiming a new artistic direction and control of her own image.

In early 2001, Aguilera reached commercial success with collaboration singles. While "Nobody Wants to Be Lonely" with Ricky Martin peaked number thirteen on Hot 100, "Lady Marmalade" with Lil' Kim, Mýa, and Pink topped the chart for five consecutive weeks. The later, included on Moulin Rouge! soundtrack, earned her the MTV Video Music Award for Video of the Year, as well the Grammy Award for Best Pop Collaboration with Vocals, for which she was also nominated with "Nobody's Want to Be Lonely". In August 2001, Warlock Records released Just Be Free, a demo album recorded by Aguilera between 1994 and 1995 while she was looking for a recording deal following the end of The All-New Mickey Mouse Club (MMC). She filed a suit against the label and the album's producers aiming to stop the release of the album. Both parties came to a confidential settlement to release the album, in which Aguilera len out her name, likeness, and image for an unspecified amount of damages.

2002–2004: New image with Stripped
With a new management, Aguilera began working in a new project while she was moving away from teen pop niche. She later cultivated a new image by adopting the alter ego Xtina, dyeing her hair black, and debuting several tattoos and body piercings. Her fourth studio album, Stripped, was released in October 2002. Containing numerous musical genres, including R&B, hip-hop, flamenco, and rock, it was described by her as "a new beginning, a re-introduction of [herself] as a new artist", for which she also contributed as executive producer and co-wrote most of the songs. The album debuted at number two on the Billboard 200, and eventually was certified five times platinum by the Recording Industry Association of America (RIAA). In the UK, Stripped sold over two million copies and became the second highest-selling album by an American female artists in 2000s. Since then, it was reported the album sold 12 million copies globally. The album's lead single, "Dirrty", peaked number 48 on Billboard Hot 100. Its accompanying music video generated controversy for depicting overtly sexual fetishes, attracting the attention of conservative organizations and moralists sought to have the video banned on MTV. The music video sparked protests in Thailand and eventually was banned in the country's local television. Aguilera's new persona was widely criticized by media outlets and it began to overshadow her music, while Entertainment Weekly described her image as "the world's skeeziest reptile woman". Although the backlash, "Dirrty" topped the charts in Ireland and the UK. The second single, "Beautiful", reached number two on the Hot 100. It received universal acclaim for its empowering lyrics about embracing inner beauty, and became a LGBT anthem. At the 46th Annual Grammy Awards, the single won Best Female Pop Vocal Performance.

Aguilera received wide media coverage due her music performances on television. At the 2003 MTV Video Music Awards, she jointed Britney Spears to performing "Like a Virgin" and "Hollywood", where both ended up kissing Madonna. Various media outlets retrospectively considered it one of the "most iconic" VMAs performances of all time.

In early 2005, Aguilera embraced a new image inspired by figures from the Old Hollywood, debuting blonde curly hair and retro-styled makeup. Her new persona eventually was adopted to promote her follow-up music project. Described as a "throwback with elements of old-school [music] combined with a modern-day twist", Back to Basics, was released as an double album in August 2006. Lirically inspired by Aguilera's husband, Jordan Bratman, it received generally positive reviews by critics due its retro-oriented production. AllMusic editor Stephen Thomas Erlewine called it "catchy, exciting, and unique ... an album to build a career upon". It debuted at number one in numerous countries, including Australia, Canada, Germany, Switzerland, and the UK. In the U.S, it scored the top on the Billboard 200, becoming her second material to lead the chart. Back to Basics was later certified double platinum by the Recording Industry Association of America (RIAA), and sold over 5 million units worldwide. "Ain't No Other Man" served as the album's lead single and was praised by music critics. The Morning Call opined that "it put [Aguilera] at Aretha Franklin's doorstep". The single peaked number six on Billboard Hot 100 and has sold 1.7 million digital copies in the U.S. Its accompanying video featured Aguilera under the alter ego Baby Jane—which was also adopted during the Back to Basics' promotion campaign. The single eventually earned her the Grammy Award for Best Female Pop Vocal Performance. Other of the album's singles, "Hurt" and "Candyman", became top-ten hits on international charts, and peaked top-thirty on Hot 100. In 2006, Aguilera also contributed vocals to singles "Somos Novios (It's Impossible)" with Andrea Bocelli and "Tell Me" with rapper Diddy, which reached number eight in the UK.

In November 2006, Aguilera embarked on the Back to Basics Tour—which visited North America, Europe, Asia, and Oceania—and ran until October 2008. Being divided in acts such as juke joint and circus, Rolling Stone hightlighted its "numerous sets and costumes changes" emphasizing Aguilera's "evolution from bubblegum starlet to dirrty vixen to her current incarnation as retro-styled soul siren". With earnings around 48.1 million in 2007, it eventually became the highest-grossing concert tour by a female of the year. Aguilera's image and "overtly sexual themes" on tour demanded the concert show in Shanghai was submitted for a prior approval by the Ministry of Culture of the People's Republic of China.

Aguilera stated that she began working in a new music material while pregnant in 2008. Her sixth studio album, Bionic, was released in June 2010. Directly inspired by electronic music, it was described by her as a project "about the future [...] my son in my life, motivating me to want to play and have fun". It received generally mixed reviews by critics which called it "very strong, but only in parts". Leah Greenblatt from Entertainment Weekly reproved it due Aguilera's "penchant for stock step-class beats and an aggressive, exhausting hypersexuality". The album peaked number three on the Billboard 200, and topped European and the UK charts. It was later certified gold by the Recording Industry Association of America (RIAA), and sold around 1 million copies globally. "Not Myself Tonight" served as the album's lead single and peaked number twenty three on Billboard Hot 100. The following singles of Bionic—"You Lost Me" and "Woohoo"—failed to reach commercial success. In late 2010, Aguilera made her acting debut in the backstage musical Burlesque, alongside Cher and Kristen Bell. She was cast as Ali Rose, an "aspiring performer from a small city who moves to Los Angeles to chase her dreams of becoming a star". Directed by Steve Antin, the film met with mixed reception from critics which described it as "campy and clichéd", although Aguilera's acting was praised. San Francisco Chronicle film critic Mick LaSalle opined that her acting was "jaw-droppingly good in several numbers", and concluded: "Aguilera knows how to listen her fellow actors, to react and be spontaneous, and it makes all the difference". She also contributed to its soundtrack, whose song "Bound to You" earned her a nomination to the Golden Globe Award for Best Original Song.

In early 2011, Aguilera received wide media coverage for ommiting a few lines while performing "The Star-Spangled Banner" at Super Bowl XLV. She apologized for the incident, saying: "I got so caught up in the moment of the song that I lost my place [...] I can only hope that everyone could feel my love for this country and that the true spirit of its anthem still came through". In April 2011, she became a coach on reality competition show The Voice, aired on NBC. Aguilera later returned to its second, third, fifth, eighth, and tenth season.

Aguilera seventh studio album, Lotus, was released in November 2012. Described as an album "about self-expression and freedom" due the personal struggles she had overcome, it mixed electropop with numerous genres. Contemporary critics called it "generic and conventional", and criticized its "digitally smothering production" which "drains all the emotion of her voice". The album peaked number seven on the Billboard 200, and produced the top-forty single "Your Body".

In 2013, Aguilera reached commercial success in collaboration songs "Feel This Moment" with rapper Pitbull and "Say Something" with duo A Great Big World.

Influences
Aguilera has named Etta James as a "role model", and said "At Last" made a major impression on her. She later stated, "I'll still be as raunchy as I wanna be, and I'll have [Etta]'s memory to back me up. She's what I want to be someday". As a young girl, The Sound of Music (1959) and its lead actress, Julie Andrews, became her early references to sing and perform, in addition to broadening her interest in Broadway. Other Aguilera's major influences include Whitney Houston, Mariah Carey, Billie Holiday, and Ella Fitzgerald. She has also cited rock bands as an influence, specifically The Red Hot Chilli Peppers, Nirvana, and Radiohead.

Aguilera also was influenced by Latin music. She later recalled singing her first songs in Spanish language during childhood, "I grew up hearing [Spanish] being spoken in my household [and] hearing a lot of Julio Iglesias on the record player". Her other inspirations in Latin music include Chavela Vargas, Vicente Fernández, and younger artists such Rosalía. As performers, Aguilera credits Madonna and Janet Jackson as major inspirations for being "positive female artists [who] aren't afraid to take chances, be daring, experimental and sexy". Cher also encouraged her to being performer and "a woman who has guts to do [everything]".

Aguilera's childhood visiting records stores molded her taste by blues and soul artists, called by her as "music that really had heart". Many artists from the genres also have been referenced in Aguilera's music, including Aretha Franklin, Marvin Gaye, Nina Simone, and Otis Redding. Her album Back to Basics (2006) features inspirations of musicians from early 20th century, as she later commented: "I was just so drawn to that [kind of music] ... Has so much pain, so much beauty of raw emotion and passion". Her other influences in the genre was added for Liberation (2018), including Michael Jackson in "Maria" and Janis Joplin in "Sick of Sittin'".

Influences also came to her from actress from the Old Hollywood. She credits it for inspiring her image, stating, "I'm fascinated with the golden age of film. I wanted to capture the authenticity of the glam era". Aguilera's references includes Marlene Dietrich, Marilyn Monroe, Greta Garbo, Veronica Lake, and the pin-up models. Her "Tilt Ya Head Back" music video recreated Monroe's signature look, while the video for "Your Body" includes a directly reference to Lucille Ball. The video for "Ain't No Other Man" also presents Aguilera under the alter ego "Baby Jane", which was inspired by Bette Davis character in psychological horror film What Ever Happened to Baby Jane? (1962). Her other inspirations came from the contemporary art, being an appreciator of works by Andy Warhol, Roy Lichtenstein and Banksy.

Voice
Critics have described Aguilera as soprano, possessing a four-octave vocal range (from C3 to C♯7). She is also able to perform the whistle register. Maura Johnston, author from Slate, opined that Aguilera's voice can be defined as "an instrument that despite its ability to leap octaves has a low-end grounding similar to that possessed by opera singers". The Boston Globe columnist Joan Anderman featured her vocal versatility, stating, "[She] is a real singer ... blessed with the sort of breathtaking elasticity, golden tones, and sheer power that separate the divas from the dabblers". In addition to sustain high notes, Aguilera is recognized for making use of the melismatic technique. Jon Pareles from The New York Times emphasized that "she can aim a note as directly as aa missile or turn its trajectory into an aerobatic spiral of leaping, quivering, and scalloping melismas". RCA Records music executive Ron Fair praised her "perfect intonation", and opined she has "pipes to be the next Barbra Streisand or Céline Dion".

Aguilera's voice also yielded comparisons with other singers. Journalist David Browne wrote that, alongside Mariah Carey and Whitney Houston, she "form the team of the main proponents" from the melismatic technique. Richard Harrington from The Washington Post shared the point of view, commenting, "She has a genuinely powerful voice that's evoked comparisons [to] Mariah Carey and Whitney Houston, though it for the most part avoids those singers' ornamental mannerisms". Sasha Frere-Jones, columnist of The New Yorker, also credited the technique by making her become "a serious singer without needing to reincarnate the Sarah Vaughan", while songwriter Steve Kipner featured her vocal dexterity, being "able to internalized all the riffs from Chaka Khan". Los Angeles Times music critic Ann Powers wrote that Aguilera posses a "voice purely powerful as that of Etta James [...] and she's moving toward the expressiveness of Gladys Knight, if not Aretha Franklin". Powers also associated her vocal ability with Donna Summer when she performs records influenced by rhythm and blues.

Aguilera, however, has also been criticized for the excessive use of melisma, as well for oversinging during her concerts shows. The Huffington Post columnist John Eskow called her as "the main proponent of oversouling". Eskow recognizes Aguilera's voice as a "great instrument", although she "[doesn't] seem to know when to stop" with the use of "gratuitous and confected melisma". Lucy Davies, music critic from BBC Music, opined that she has "a stunning voice", but indicated: "She could be more varied, simply by cutting out some of the 'ye-e-eeeh, woah' in her songs". Writing for Entertainment Weekly, Chris Willman credits Aguilera's tendency to oversinging as an influence of Mariah Carey, noting "her slightly nasal tone that really only becomes obvious when she's overselling a song". Alexa Tietjen from VH1 acknowledged that Aguilera "does tend to take it to the extreme at times [...] but her vocal prowess is what's gotten her so far. Love them or hate them, the riffs are a part of who she is as performer".

Composition and musical style
Aguilera's music has been the subject of analysis. Critics acknowledged domestic violence experienced during childhood as one of the main topics in her music. Mary Anne Donovan, author of Christina Aguilera: A Biography (2010), noted that she "channeled her fear and sadness away from the abuse in her family to instead create the music that became her art and her livelihood". It also influenced Aguilera's transition to adulthood and impacted many of her songs, whose lyrics references female empowerment. In a 2006 interview, she commented: "I feel a responsibility to share some of these things that aren’t kind of the brighter sides of my life [...] People that can relate might not feel as alone in the circumstance".

Aguilera also has often defended sex-positive movement and denounced social double standards in her music. Reviewing Stripped (2002), Sophie Wilkinson from Vice opined that its music "explores nuanced articulations of sexual desires and fears all while highlighting the social double standards", in addition to give "any woman the confidence to take charge of her sexuality and ownership of her body". Jennifer K. Armstrong, author of Sexy Feminism: A Girl's Guide to Love, Success, and Style (2013), opined that her music has "reject[ed] the double standards set forth by sexism and patriarchy".

Chin Wai Wong from Hollins University also observed topics such as romance, introspection of vulnerability, gratitude for support, and sexual liberation in Aguilera's music, representing "multi-dimensional aspects of life [and] different social responsibilities a woman experiences". While critics noted the feminist message in her works, Aguilera was acknowleged due her "refusal to sanitize her own sexuality to meet either the norms of mainstream gender politics or mainline Feminism's resistance". The Guardian journalist Hermione Hoby opined that she "incites a sisterly spirit of collaboration [and] not shy of the odd feministic declaration herself". Other themes boarded in her lyrics includes self-respect, body image, and LGBT rights, in addition to "fighting for creative freedom and gender equality".

Aguilera's discography is generally categorized as pop, contemporary R&B, soul, and hip-hop. According to critics, she also have experimented with other musical genres in her works. In a 2008 interview, she explained about "always [being] inspired by new things" in music and "experimenting with [her] voice". Alexis Petridis from The Guardian considered the "boldness in reinventing" continually her music as "one of her most impressive facets" as an artist. Initially established as a bubblegum pop singer, she mixed teen pop and dance-pop on her first records, Christina Aguilera (1999) and Mi Reflejo (2000)—which also takes inspiration in numerous genres from Latin music.

Moving away from the teen niche, Aguilera's post-2000 material mainly incorporated R&B and hip-hop. Listed as an executive producer on Stripped (2002), she mixed both genres with Latin pop, rock, neo-soul, gospel, among others, while Back to Basics (2006) was described as a "throwback with elements of old-school genres combined with a modern-day twist [and] hard-hitting beats". She continued merging both R&B and hip-hop with other musical styles on Burlesque (2010) and Liberation (2018), which also features soul and blues elements.

The show tune "Lady Marmalade" is noted as Aguilera's first musical transformation. Referred to as "too urban" by RCA Records executives, the song transitioned her music "from teen pop to a more mature sound".
