A shrewd investigative eye reveals the following theory about the sexy Gossip Girl ads for Season Two - someone in the CW marketing department spiced up an already-hot show even more by making Blair Waldorf naked!

Compare the advertisement for "A Nasty Piece of Work" with a photo from the episode "School Lies" which aired earlier this year:

Of course, there's also the theory that this is a NEW photo, and Blair is indeed topless (and possibly bottomless as well) with a new man this season.

What do you think, Gossip Girl sleuths? Is that Blair and Nate? Is she skinny-dipping in a new photo or is this photoshop at its best?
