We posted some Gossip Girl set photos earlier today (including the visit to the set by Tyra Banks), but this one deserves its own post. Check out the classic facial expression of Ed Westwick's Chuck Bass here. Wonder what he's thinking right now ...

That look is vintage Chuck Bass. That dress? Stylish Little J!

He's with Blair Waldorf now, but one never knows what Chuck Bass - seen here with Jenny Humphrey (Taylor Momsen) has up his sleeve. Or what that mind is thinking.

UPDATE: Below is a video of the scene they were filming. See if you think this sheds any light on what happens, or just leaves you asking the same questions ...
