Gossip Girl Cast Sings About Love, Acts Out College Lust

Hilary Duff, Ed Westwick, Jessica Szohr and Taylor Momsen were back to work on Gossip Girl Tuesday after most of them hit the red carpet together to support Penn Badgley's new thriller The Stepfather. Leighton Meester missed the premiere, but was out yesterday to debut her new song "Somebody to Love" all over the airwaves. Blair Waldorf has her somebody to love, but next week we'll see what happens with a certain Chuck Bass kiss — maybe it will even give us a clue as to who's involved in the mysterious upcoming threesome.
