Looks like everyone in the Gossip Girl cast is making headlines this week.

Two cast members were spotted smooching at the show's holiday party - and it's not who you think. Chace Crawford and Taylor Momsen, ages 23 and 15, respectively, are at the center of the latest kissing session, according to Page Six.

A Page Six spy spotted the co-stars sneak away during their holiday party at Haven on East 51st Street to steal kisses in the corner, though Crawford's rep denied the story.

Now that would be even more scandalous than Nate and Jenny!

We have no idea if this latest Gossip Girl rumor is true or not. But Taylor Momsen (Jenny) and Chace Crawford (Nate) certainly have experience locking lips!
