Drama on the set of Gossip Girl! Buffy the Vampire Slayer alum Michelle Trachtenberg isn't straying far from the CW. The actress just confirmed that she will guest star on at least four episodes of Gossip Girl beginning in May, according to the Hollywood Reporter. Trachtenberg has signed on to play Georgina Sparks -- a blast from Serena Van Der Woodsen's dark past. A troublemaker and a manipulator (even by the Upper East Side crew's standards), Sparks arrives back in Manhattan from rehab to shake things up. According to the Reporter, Mischa Barton was rumored to be up for the role. --Brian Orloff
