Buffy's Dawn to join Gossip Girl

The web's abuzz with rumors of Buffy alum, Michelle Trachtenberg, joining the cast of Gossip Girl. The show returns to airwaves in April if I'm not mistaken, after being screwed over by the writer's strike. I'm excited; I love Dawn! I hope she plays a bitch and f**ks with Serena's s**t!! Can't wait ^_^
