Gossip Girl Sneak Peeks: Is That a Baby Bump Under There?

Get four previews of Monday's all-new episode of the hit CW series

Spoiler Alert! Could yet another OMFG moment be on the way to Gossip Girl?

First we break the news that Bart Bass (Robert John Burke) is coming back.

And now, this is just a crazy unconfirmed theory, but: Could Olivia (Hilary Duff) be pregnant?!

One peek at the footage above from next week's Gossip Girl and you'll see:

1. Olivia and Dan are spending a lot of time doing the dirty.
2. Naked. Between the sheets.
3. According to Quinn Fabray on Glee, it takes far less than that to make a baby.
4. Olivia mentions she is craving ice cream! (OK, gelato, but we hear that's a similar specimin for glamorous prego types.)

OK, so that's probably totally not true. Olivia is not pregnant. But still, stranger things have happened on this show (see: Bart Bass). And regardless, the Duffster sure seems to be hiding a lot. Can Dan take it?

Meanwhile, Blair and Serena are totally breaking up, and trading up. See for yourself in the clips below...
