The characters on Gossip Girl are privileged enough to attend all kinds of upscale parties, and last night the show's stars got all fancied up for the 11th Annual HELP Group Teddy Bear Ball. The benefits of the event go to a nonprofit that helps kids with autism and other special needs. Blake Lively kept it simple in her embellished LBD while Leighton Meester looked like a present in her gold festive dress. Chace Crawford was his usual pretty self and we wonder if he and Leighton snuck in any scandalous kisses. We have a feeling the drama level wasn't quite on par with the masquerade ball, but it was for a much better cause.
