Tonight’s Gossip Girl is sure to stir things up, what with Michelle Trachtenberg playing Georgina Sparks, the mean girl who’s back to teach the girls a lesson. Watch Michelle talking about how she was cast for the role and her insights into the show, on Fancast. If you’ll notice Michelle’s subtle words in the video, it seems like she didn’t really watch the show before she was cast. Sounds like a mean-girl backhanded comment to me!
