Last night, the cast of Gossip Girl kicked off the show's second season with a fete at chi-chi emporium Henri Bendel (with YSL Beaute) on Fifth Avenue. And look how much fun they had! Although Blake was MIA (boo!) as was Penn (double boo!), Leighton, Taylor, Jessica and Kelly did everyone's favorite guilty pleasure proud. The Good, The Bad, and The Anna Sui - after the jump!
