It's lead single, "Don't Cha" topped the charts in multiple countries around the world including in Australia, Canada, Ireland, New Zealand, Switzerland and the United Kingdom. The following single "Stickwitu" became the Dolls' second consecutive UK number-one single. The song received mixed reviews noting that the song lacked a catchy hook like its predecessor "Don't Cha". The song was later received a nomination for the Grammy Award for Best Pop Performance by a Duo or Group with Vocals. Its fourth single "Buttons" topped the chart in New Zeland, while reaching the top-three in the United States, Australia and United Kingdom. In the U.S., the Dolls became the first all-female group in digital history to have three singles (along with "Don't Cha" and "When I Grow Up") to pass the two million mark in digital sales.

In December of 2006, the group was selected by the National Basketball Association and ABC to record the opening number for the ABC's coverage of the NBA using an adaptation of its track "Right Now" for the musical segment, which will also be previewed going into and out of commercial breaks during telecasts.

2008–09: Doll Domination and line-up changes
Continuing as a quintet, the Pussycat Dolls second studio album Doll Domination was released on September 22, 2008. Described as the "Pussycat Dolls to the next power," Kimberly Wyatt stated, that the album would contain uptempo and fun songs "but there's also songs that show the sensitive side of the Pussycat Dolls". The albums release was preceded by its lead single,"When I Grow Up" which was debuted for the first time at the Jimmy Kimmel Live!. The song managed to peak at number nine on the Billboard Hot 100. The song also made the Pussycat Dolls become the first all-female group in digital history to have three singles (along with "Don't Cha" and "Buttons") pass the two million mark in digital sales. Their following single "Whatcha Think About That" which features rapper Missy Elliot, failed to match the success of the previous single in North America, however the song managed to peak at number nine in United Kingdom. Upon release Doll Domination recieved mixed reviews from most music critics; according to the music review aggregation of Metacritic, it garnered an average score of 51/100 which which indicates "mixed or average reviews". The album spawned two more singles, the melodramtic-"I Hate This Part" and the robotic "Bottle Pop" which both peaked at number one on the Hot Dance Club Songs chart. On January 2009 they embarked their second world tour called Doll Domination Tour to support Doll Domination. In mid-2009 they opened for Britney Spears' tour The Circus Starring Britney Spears on the first leg in North America.

In April 2009 Billboard said that Doll Domination which sold 400,000 copies so far in the U.S. Following the commercial disappointment of the album Scherzinger confirmed that the album would be re-released to give more people a chance to get their music. The re-leases spawned two more singles: the English version of "Jai Ho! (You Are My Destiny)" and the dance remix of "Hush Hush" (retitled "Hush Hush; Hush Hush") Both singles were billed as "Pussycat Dolls featuring Nicole Scherzinger" which caused tension within the group including one by Thornton during one of the group's appearances on tour.

Following repeated media speculation and growing tension within the group Thornton clarified the situation to MTV News that the group is on "a much-needed break". Meanwhile on an interview with MTV News, Robin Antin revealed that that after their hiatus, there will be some "new faces" joining frontwoman Nicole Scherzinger. Since then Wyatt has been very vocal saying her "role in group was a job at the end of the day and that they all had individual lives to live" and saw Scherzinger as "a business associate".
