'Gossip Girl' Star Leighton Meester Dishes On Gay Kiss, Lady Gaga

'I sort of make the kiss happen. I can tell you that much,' Meester says.

"Gossip Girl" is about to step up its love game on Monday (October 19), when Ed Westwick's Chuck Bass will start playing for the other team and kiss a boy on the show. There's no word on how much he'll like it, but his onscreen girlfriend, Leighton Meester, divulges that her character, Blair Waldorf, just may be the mastermind behind the show's much-hyped gay kiss.

"Well, I guess that I can tell you some things," she conceded while on the set of her new music video for her duet with Robin Thicke, "Somebody to Love." "No, it's not tied into a threesome. I think all of this is just so everybody grabs their attention, and we're all in college now, so we can definitely push the limit with the sexuality, which is fine by me. I sort of make the kiss happen. I can tell you that much, and that's it."

As if the show's latest steamy storylines weren't attention-grabbing enough, [artist id="3061469"]Lady Gaga[/artist] will also be making an appearance later this season. "I don't know what I can say, and what I can't," Meester said when pumped for details on the cameo. "It was really cool. It was very avant garde and kind of gothic, and she's pretty cool, so it was very fun."

Though Penn Badgley suggested last week that Gaga would have something to do with Dan Humphrey's storyline, Meester clarified: "She just makes a cameo performance, and we talk about her for awhile," she said. "But, yeah, we all have a storyline where we put on a cabaret with her songs. You'll have to wait and see."
