Sebastian Stan Describes On-and-Off Set Romances

Leighton Meester and boyfriend Sebastian Stan may not be friendly on Gossip Girl, but in real life, he feels fortunate to be in a relationship with her.

“I’m a really lucky guy,” Stan, 25, said at the premiere of Taking Woodstock in New York City on Thursday. “Leighton is the most interesting, sophisticated, talented and extremely funny person that I know. She’s really hilarious.”

While Sebastian Stan gives his costar Ed Westwick the evil eye when his character Chuck Bass gets to make out with Meester’s Blair Waldorf, it’s all in jest - and he says everyone always remains professional when it comes to romantic scenes.

“It’s work and everyone shares the same mentality when it comes to that. We all laugh about it,” he says. “The good part is I get to go home with her.”

On Gossip Girl, Carter Baizen may be putting the moves on Serena van der Woodsen, but in real life, Sebastian Stan's heart is with his co-star Leighton Meester.

Besides, Stan gets his own kissing scenes with Blake Lively in the upcoming Season Three, which returns September 14. In preparation, the actor skips the breath mints and goes for an unconventional route of eating fruit before he puckers up.

“I try to stick to apples and pears to keep it more interesting,” he said.

Stan says that when his character Carter Baizen’s background is revealed, it will stir up trouble with the Upper East Siders - especially Serena van der Woodsen.

“They are revealing his history, where he comes from,” says Stan. “His whole background involves Serena’s character. It’s different from the other relationships.”
