The Gossip Girl stars were out in force to celebrate the premiere of Penn Badgley's first big film - The Stepfather.

OMG little Dan Humphrey's all grown-up and got himself a proper film role!

Yes, GG's Penn Badgley is the leading (hot) man in new horror The Stepfather.

It's not out over here until December 4th, but at the premiere last night in New York all the GG cast were there with one exception.

Yep, that's not Blake Lively with a face transplant, it's Penn's co-star Amber Heard.

If we were the gossiping type, we might say that girlfriend Blake's no-show was a sign that Penn and Blake are on the rocks....

Yep, Chace Crawford was there - along with Taylor Momsen, Ed Westwick and Jessica Szohr - but you don't want to see pics of them do you?

We know you're all about the Nate-love

HOT!

Oh and if you haven't seen it, here's a trailer of Penn's film The Stepfather. IT'S SCARY!

Comments please!
