Elizabeth Quinn Brown

Lily, Charlie and Serena eagerly anticipate the Studio 54 party being thrown in CeCe's (recurring guest star CAROLINE LAGERFELT) honor. Nate takes on a new role at the Spectator, but his first big story turns out to be about someone he knows all too well. Blair turns to an unlikely person for help.

Blair makes all of her former minions and Charlie compete to secure the coveted bridesmaid spots in her upcoming royal wedding. Nate is tired of keeping his relationship with Diana (recurring guest star ELIZABETH HURLEY) a secret, so he decides to use Charlie to make Diana jealous. Serena's boss, Jane (recurring guest star MICHAEL MICHELE) is determined to acquire the film rights to Dan's book, so Serena must put her personal feelings about Dan and the book aside in order to close the deal.
