The CW announced in December 2010 that Baldwin would return in February 2011. Sheila Kelley replaced Illeana Douglas as Lily's sister, Carol, after Douglas was forced to drop out of the project due to scheduling conflicts.

Plot
Season four begins with Serena and Blair enjoying their summer in Paris, until the unexpected appearance of Chuck Bass, who is using a false name and cozying up to a new girl. Blair has to decide if she wants to fight for Chuck or spend her energy trying to rule Columbia University. Serena needs to choose between Nate and Dan, but Dan is a bit busy coping with his new role as "dad" to Georgina's baby. Georgina later reveals the baby is not his. Stephanie Savage revealed in an interview that the Dan and Serena story is "reactivated" and sorting through it will become a bigger story. She also revealed that the third-season finale "Last Tango, Then Paris" had a big impact on Jenny and she would be a changed person when she returns. Her return later this season would be "full of drama".

The Gossip Girl website was under construction when Serena and Blair returned from Paris and debuted "never before seen technology" when it returned. It is revealed that Juliet is working with her brother to take down Serena, for unknown reasons. Vanessa gets caught in the middle when Juliet sets her up for stealing Serena's phone and sending an incriminating email. Vanessa later leaves town when only Dan believes her, but tells Juliet to watch her back. After Blair ran Chuck's new girlfriend out of town, he pledges war against her. They later decide that it is best for both of them if they end their fighting after Jenny posts on Gossip Girl the reason why she left town. In the next episode, at Blair's 20th birthday party they kiss and have sex. Both Nate and Dan still have feelings for Serena, but do not know what to make of her mixed signals.

Most of Juliet's plan is revealed by the end of the first half of the season, with some elements set to carry over. Juliet also recruits two main characters to help take Serena down. Blair and Dan team up to help Serena. The two characters who joined Juliet were Vanessa and Jenny. The three manage to turn everyone against Serena when Juliet and Jenny dress up as her at a masquerade party. Juliet takes photos of herself with cocaine and drugs Serena, causing Lily to believe Serena had gone off the rails again and has her committed to the Ostroff center. Jenny, feeling guilty about what they have done, reveals everything to Blair. Vanessa leaves town to avoid Blair, while Blair and Dan form an alliance to seek revenge on Juliet. After they track her down, Juliet goes to Serena and explains everything to her. It is revealed in a confrontation with Lily that Juliet's brother Ben was Serena's former teacher at her boarding school in Connecticut, who was accused of having an affair with Serena. Lily forged Serena's signature on the police affidavit, which in Lily's plan, would allow Serena to return home and, inadvertently, had sent Ben to prison. Serena then hatches a plan to help free Ben from prison. This involves proving that her mother forged the affidavit against Ben. Chuck also learns that Lily was planning to sell Bass Industries behind his back.

Reception
The season opened to a 1.0 Adults 18–49 rating and 1.84 million viewers. The fourth episode initially hit season highs in all categories with a 2.8 Women 18-34 rating, 1.1 Adults 18–49, a 1.7 in Adults 18-34 and 2.00 million viewers, until the airing of the eleventh episode hit a season high in viewers 2.06 million. The series has larger increases in the adults 18–49 on the Live + 7 DVR Ratings. The 4th episode had an 18–49 rating of 1.1, which was later increased to a 1.5 rating. The 5th episode had an 18–49 rating of 0.9, which later rose up to 1.3, which is 44% of increase.

The season premiered to generally favorable reviews from critics. Steve Marsi of TV Fanatic gave the episode 4.5 stars out of 5.0 and praised Michelle Trachtenberg's and guest star Katie Cassidy's acting and storylines. Mark O. Estes, from TV Overmind, also enjoyed the fact that the episode had "explored more adult themes than usual." Gerard McGarry, from Unreality Shout, said that the season premiere was "brilliant", while Alexis James-blackhead, from Buzz Focus, said that the episode was "less sizzle than fizzle." Leighton Meester and Ed Westwick's performance was praised during the next episode "Chuck Bass" was also a trending topic on Twitter on the night the episode aired. The season has a 75/100 score of Metacritic, indicating mostly positive reviews.

Erik Adams from The A.V. Club reviewed the direction of the fourth season following the fourth-season premiere. "By the time a television show reaches its fourth season, the characteristics of its main ensemble ought to be deeply entrenched and immediately recognizable to regular viewers. But on the occasion of Gossip Girl's fourth season première, the ongoing teen soap—and its characters—are allowed some reinvention. The CW's flagship franchise is in a precarious position: it's a show that's both out of time and losing its sizzle." Adams cited the show's expensive art direction despite the economic woes outside of the show and the doubtful following of the Gossip Girl world considering the rise of micro-blogging in celebrity culture. Adams praised the development of Blair and Serena's relationship, declaring their friendship as "the great, central romance of Gossip Girl."

Brian Cantor of Headline Planet expressed disappointment with the show's performance for the season premiere, stating "[Gossip Girl] considerably [has] less critical interest and buzz than there had been for past seasons; the show no longer even has the 'pop culture phenomenon' claim to soften the blow of ratings releases." Judy Berman of the Los Angeles Times in contrast, defended the show's creative form during the midseason finale "The Townie", stating, "Whenever I start to think that the show has run out of material [...] it unleashes a showstopping hour of sparkly melodrama that reminds me of why I'm still watching." With the airing of the season finale TV Fanatic's Steve Marsi assessed the fourth season stating that "it's not a stretch to say the past season was uneven at best, lacking some of the continuity, humor and drama of the past. It's hard to put one's finger on in a sense, since many episodes were enjoyable. But there was a certain OMG-can-you-believe-this-happened factor that just wasn't there."
