Gossip Girl season 5

Serena finds a job as a production assistant while spending her summer in L.A, but her work is quickly jeopardized when she tries to impress her new employer in order to be promoted. Nate and Chuck also arrive in Los Angeles, where Nate meets an older woman and Chuck starts making increasingly reckless moves. Meanwhile, after spending the summer in Monaco, Blair returns to New York to hasten the preparation of her wedding, while concealing a secret that could wreck it all. Meanwhile, Dan seeks Louis' help in preventing the publication of a revealing article on Blair written in the spring.

Blair tries to conceal the news of her recent pregnancy from Louis as the arrival of her future sister-in-law Beatrice (Roxane Mesquida) nears. Nate reconnects with the mysterious Diana Payne (Elizabeth Hurley), a woman whom he had a fling with in Los Angeles who offers him a job opportunity to work at her newspaper, The New York Spectator. Meanwhile, Dan is desperately in need of help from Chuck to stop his novel from being published, but finds out that Chuck is hiding a secret. Ivy, still in character as Charlie, tries to hide her real identity from an unsuspecting Serena but her plans affects her life in Los Angeles with her unsuspecting boyfriend Max. Blair's plan does not go accordingly since Beatrice overhears her tell Dan that she is pregnant, not bulimic.

Serena and Charlie return to New York. Worrying that her identity will be revealed, Ivy decides to start forging her own path by becoming a part of New York's social scene as Charlie. Meanwhile, Dan learns that his former mentor, Noah Shapiro, is responsible for publishing his novel. After his attempts at stopping Noah fail, Dan soon ends up in the spotlight. Chuck tries to break through his emotional block. Unknowingly, Nate is persuaded by the ruthless maneater Diana to cross moral lines while interviewing a couple at the Jenny Packham fashion show. Lily is finally released from house arrest and attends the fashion show with Rufus, despite the fact that her social life is in shambles. After learning that Ivy stole some of Charlie's trust fund money for herself, Carol Rhodes tracks down Ivy to New York where Ivy threatens to reveal their scam, as well as implicate Serena and the entire Van Der Woodsen family, if Carol does not back away. Elsewhere, a very reluctant Blair decides she does not want to learn who the father of her unborn child is, but is later seen telling Chuck that she is pregnant with Louis' baby, but adds "Part of me wished it was yours". He is both amazed and hurt. When Blair tells Louis that she is pregnant, he is ecstatic, but at the end Blair is seen hiding the paternity test results in a drawer. Also, Nate finds Ivy's missing cell phone with her text messages from her boyfriend Max, but does not make the connection that Ivy and Charlie are one and the same.

Dan is about to be announced as author of Inside so he gives copies of the book to Blair, Serena, Nate, Chuck, and Rufus, hoping they will be supportive at his upcoming book party. In the book, Dan described Serena as the "old Serena": drinking, dating teachers, being shallow, partying, and reckless. Nate does not receive a character description, but is merged with Eric (a younger, gay character with political relatives). Chuck is described as being lonely, cynical and without any friends or family. The book talks about Blair and Dan having sex, and when Louis reads it he says he cannot trust Blair anymore. Blair is afraid she will have to raise the baby on her own if he leaves her. In the end, Louis apologizes for his behavior and agrees to trust Blair. Even Rufus becomes angry and alienated with Dan when he says he had never regretted leaving the music industry to have a family, until upon reading the book, which portrays him as marrying Lily just for money. Meanwhile, Diana makes the connection of Ivy and Charlie being the same person and forces Charlie to work for her at The Spectator. Also, Serena's boss tells her to get the film rights for Inside and that she has only one week, forcing Serena to choose between Dan and her career.

Louis' mother Princess Sophie and his sister Beatrice pay another visit to New York where Blair announces her pregnancy to everyone. While her stepfather and mother, Cyrus and Eleanor, decide to throw a Yom Kippur dinner party to celebrate, Sophie and Beatrice try to get Blair to accept a series of conditions following the marriage. Blair naturally refuses, and Louis must choose between standing beside Blair or his mother. Meanwhile, Serena tries to get back into Dan's good graces after her boss tells her to ask Dan to gain the movie rights to his book. Charlie asks Nate for help after Diana gives her a difficult assignment to find more dirt on the Van der Woodsen family kept in the family safe. As Rufus and Lily continue to avoid talking with Dan over his book, Chuck connects with an attractive therapist who rebuffs his advances and seems to see right through his character for who he really is.

Blair tries out three of her former minions to see if they are worthy to be her bridesmaids, and Charlie willingly teams up with the group in order to seek out a story, where she proves herself to be more than a match for the mean girls. Nate becomes frustrated that Diana refuses to publicly speak about their romance. Nate tries to make Diana jealous by asking Charlie to accompany him to Diana's party celebrating the opening of her new gossip blog at The Spectator. Meanwhile, Serena is forced by her boss, Jane, to secure the screenwriting rights for Dan's book, who quickly realizes that Jane wants someone else to write the screenplay in order to make the movie more marketable. Also, Chuck discovers that his therapist, Dr. Eliza Barnes, has been recruited by Louis in order to dissuade Chuck from pursuing Blair any further.

Several of the group attend a performance of Punchdrunk's provocative theater experience, "Sleep No More", which involves masks, anonymity and some surprising romantic twists by the end of the evening. Dorota follows Blair to the performance to stop her from trying to prove that Chuck's attempts to reform himself into a better man are a scam. Meanwhile, Diana sets her sights to snag Serena a job at The Spectator as part of her twisted quest to ruin Gossip Girl's website. Charlie/Ivy's ex-boyfriend, Max, arrives in town to look for her, and ends up as Serena's date to the performance. Diana sets about manipulating Max, Serena, Charlie, and Nate, hoping to cause a major confrontation for her own deranged enjoyment. Elsewhere, Dan sets out on his book tour, but Rufus and Lily discover that he is not exactly having the experience that he claims. At the end, more shocking twists are revealed as the evil Diana and Nate's crooked grandfather, William van der Bilt, are revealed to have been working together to orchestrate Nate's employment with Diana as part of sinister grand plan for Nate, while Max, sent away by Diana on a ruse, accidentally discovers Ivy's double life of impersonating Serena's cousin Charlie.

Serena is hard at work planning a dream bridal shower for Blair, but it is no surprise that Serena has to plant some false information about the shower in order to keep Blair from finding out all the details. Meanwhile, Chuck and Dan decide to spend the day together to distract themselves from the fact that they did not make the invite list for Blair's shower. Nate and Serena find a silver bullet in Diana's war against Gossip Girl when they uncover a list of all of Gossip Girl's contacts, but struggle about whether to use it or not. When the list is leaked anyway, Nate and Serena accuse each other. Nate also accuses Diana, but Blair finds out that the culprit is Louis. Elsewhere, Max confronts Ivy about her double life of impersonating Charlie. Max quickly sees through Ivy's lies and, instead of informing Lily or Serena or the authorities with what he knows, he blackmails Ivy for a large sum of money. Also, William van der Bilt forces Diana to quit as editor-in-chief of The Spectator so that Nate can take her place. Chuck tells Dan that he (Dan) is in love with Blair. The episode ends with Blair visiting Chuck at the Empire after she learns from Serena that Chuck really has changed.

CeCe Rhodes arrives back in New York where Lily and Serena are planning to throw her a Studio 54 party in her honor. Serena continues dating Max who begins blackmailing Charlie. Meanwhile, Dan meets with his publicist Alessandra where they create rival "Dan fan" and "Dan hater" accounts on Twitter in order to create online buzz for his book. Blair attempts to figure out how to make Louis more like the "new" Chuck by spending the day with Chuck. She accompanies him to therapy and demands to know how he has improved himself only to find out that he has let her go. Upset, she runs home and later reveals to Chuck that she is afraid that she is the one that brings the dark side out in him and Louis. Chuck assures her that she is "the lightest thing that ever came into my life" and tells her he let her go because she asked him to. He just wants her to be happy. Also, as Nate becomes the new boss of The Spectator, one of his employees finds out that his cousin Tripp's wife, Maureen, might be having an affair. He soon figures out, however, that Maureen is faking an affair in order to create a sympathetic image for Tripp in the public eye before the upcoming election. Serena learns the truth about Ivy and Max and breaks up with him. Carol Rhodes visits to help find a cover story to get "Charlie" her trust fund and to help keep her there where she is loved. In the final confrontation, everyone believes Ivy's false story that she really is Charlie and pretended to be Ivy when she was with Max, even though he calls her a liar and says otherwise. Ivy also finds out that CeCe is sick, but keeps it a secret. The episode ends with Max reaffirming his threats to Ivy to expose her scam, Chuck telling Nate that he still loves Blair, and Blair looking despondent in her bedroom, refusing to talking to Louis who is out of the country.

Serena and Lily prepare Charlie for her first debutante ball to welcome her into New York high society, but the vindictive Max is determined to reveal Charlie/Ivy's secret by any means necessary. Meanwhile, Blair must choose where she stands with both Louis and Chuck as she hides out at the Humphrey loft in Brooklyn from the press. Dan realizes that it is time to tell Blair the truth about his feelings for her. Louis returns to New York where he meets with Serena and confides in her about his fears about his future with Blair. Nate learns that his grandfather, William van der Bilt, owns the majority of stock shares at The Spectator and he influenced Diana to hire him. William invites Nate to an upstate retreat, but Nate's cousin, Tripp, has been excluded. After Dan sacrifices his own love for Blair for her happiness, Chuck and Blair are hurried into a car from Charlie's debutante ball. Their car is tailed by vicious paparazzi (Charlie sent a blast to Gossip Girl and tipped them off in order to keep them away from her) who cause them to crash, leaving Chuck fighting for his life and the pregnant Blair fighting to keep her baby. After Max's pleas to both Serena and Nate about Charlie's real identity fall on deaf ears, he runs into Tripp van der Bilt, whom he tells Ivy’s story to. Charlie calls Carol Rhodes to tell her that she is leaving New York City after she tells Rufus that she is a fraud. Also, Diana is called by Jack Bass and informed about Chuck and Blair's car accident; she is somehow involved.

Through a series of emotional flashbacks, Blair reveals to Serena what really happened in the aftermath of her car crash with Chuck. Dan tries to help Blair recover, while both Chuck and Louis mistake their bonding as an affair. Meanwhile, Nate discovers information about the accident that suggests possible foul play. Having successfully shut down Gossip Girl's website, Serena is reluctant to become the next Gossip Girl as her work at The Spectator takes off. Elsewhere, Lily is worried by Charlie's long absence and decides to hire a private detective to track her down despite Rufus' objections. Vera Wang makes a cameo as herself at Blair's dress fitting.

Blair decides to throw herself a bachelorette party, but shady enemies who include Beatrice (Roxane Mesquida) and her co-conspirator cousin Father Cavette, scheme to ruin and humiliate Blair, with an unknowing Chuck as their patsy, in order to prevent Blair's upcoming marriage by any means necessary.

During the wedding, Gossip Girl leaks a video which shows Blair confessing her love for Chuck. However, the interrupted wedding continues and Blair is officially declared the Princess of Monaco. However, at the reception, Louis reveals to Blair that the wedding stands is just for show and their love does not exist anymore, to which Blair reacts in distress and runs away with Dan. The identity of Gossip Girl's successor is revealed at the end of the episode.

Following the wedding, Blair tries to leave for the Dominican Republic, with the help of Dan, to get a divorce from Louis without his consent due to a loophole in the Dominican Republic's law. However, she realizes that she forgot her passport and so asks Dorota for help.

Elsewhere, Nate has another meeting with the real Charlie Rhodes, who goes by the name of Lola.
