Belles de Jour (S04E01)

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. Plus, Dan's baby mama drama continues with Georgina (recurring guest star Michelle Trachtenberg- Buffy the Vampire Slayer) and the van der Woodsen apartment is buzzing with activity as a ""Fashion's Night Out"" event is planned.
