Cool. Michelle Trachtenberg is set to guest star on multiple episodes of Gossip Girl.

Michelle Trachtenberg once graced our TVs on Buffy the Vampire Slayer — and now, she’s back for at least four episodes of Gossip Girl, starting in May.

Michelle Trachtenberg will play troublemaker Georgina Sparks, who returns to Manhattan following rehab, and naturally messes up Serena Van Der Woodsen’s (Blake Lively) life.

This is the Gossip Girl role that Mischa Barton was rumored to have declined.
