High society and low blows are back as Gossip Girl continues for its much-anticipated fourth season. Last season ended with a bang as a heartbroken Chuck Bass (series star Ed Westwick) lay bleeding in the streets of Prague while Blair Waldorf (series star Leighton Meester) and a newly single Serena van der Woodsen (series star Blake Lively) jetted off to Paris for a fabulous summer abroad.
Meanwhile, Nate Archibald (series star Chace Crawford), fresh off his painful breakup with Serena, decided to take a page out of Chuck's playboy playbook just as Dan Humphrey (series star Penn Badgley) discovered he was going to have to settle down and be a father....
01 - Belles de Jour
Season four kicks off in the City of Lights - Paris! Blair has spent a fabulous summer in Paris without realizing Chuck, her former love, has been shot. Yet as much as Blair tries to distract herself from the pain Chuck caused her by sleeping with Jenny Humphrey (series star TAYLOR MOMSEN), his mysterious appearance in Paris with a beautiful new woman (recurring guest star CLÉMENCE POÉSY - upcoming 127 Hours, In Bruges, Harry Potter and the Goblet of Fire) will force both of them to face what happened. Serena has been enjoying a Parisian summer of love with boys, Blair and Balenciaga as she tries to avoid the inevitable decision about which of her two longtime beaus, Dan or Nate, she should return to. Meanwhile, back on the Upper East Side of Manhattan, Nate meets an intriguing girl, Juliet (recurring guest star KATIE CASSIDY - Melrose Place, Supernatural), who helps him realize that his summer of sexual conquests was his way of avoiding his unresolved feelings for Serena.
