Penn Badgley On Kissing 'Gossip Girl' Co-Star Leighton Meester

That Dan Humphrey sure gets around. He's managed to fling with BFF Vanessa and step-sister Serena, and these days he's getting busy with the Queen B herself, Blair. When MTV News caught up with the "Gossip Girl" star at Cosmopolitan magazine's 2011 Fun Fearless Males party, Penn Badgley shared what it's like to work so intimately with Miss Leighton Meester.

"It was actually the most fun I had had on the show in a while," Penn dished about his latest on-screen romance. "It was something new for my character, and I was having fun with the rapport, and I think my dialogue benefited from it. It was actually a lot of fun to work with Leighton. I hadn’t much. We were like the only two who had never really interacted."

Well it seems they've quickly gone from 0 to 60 in the interacting department, and Penn admitted he's not complaining. "It was great We all get along pretty impeccably, even after four years," he shared. "I mean there are ups and downs, as there are in anything. It's great. I've actually really enjoyed working with her."

With Dan and Blair busy being Dair, what does that mean for his past ladies, like Serena and Vanessa? Well, he says, you'll never believe what happens next. "I don’t know how much I can give away," he teased. "It doesn’t end the way you think it does. I can't say much."
