Blair Waldorf's pregnancy was revealed to several, but not all characters on last night's Gossip Girl (see our review from earlier). What no one knows, including B herself, is who the father is.

Now, here's a new mystery for you, courtesy of E! Online:

Next week, the beautiful B totally makes out with a guy.

A guy that is NOT the prince OR Chuck. While we caution that this scene "is not what it seems," it is not a dream.

Confused/intrigued yet? Make of that what you will and sound off with Dair-related theories for next week below.

Regarding who is gay in Dan's book? It's not Serena. It's not Chuck. That's all we have for now on that front, but rumor has it Rufus in particular is extremely displeased by Dan's book. So ... there's that.

Who's the father of Blair's baby?
