Leighton Meester, Penn Badgley Reveal Details About 'Gossip Girl' Threesome

Michelle Trachtenberg adds, 'It's actually going to be, like, a tensome.'

The highly controversial "Gossip Girl" threesome is about to go down on Monday night's (November 9) episode of the saucy teen soap. And, with so many of the cast being possible suspects in the naughty storyline, it's only a matter of time before we know who hooks up. And with [movieperson id="472728"]Ed Westwick[/movieperson]'s Chuck Bass already having shared a kiss with a guy on the show, the threesome will probably be even more provocative.

[movieperson id="306341"]Penn Badgley[/movieperson] recently threw his name into the threesome ring when he teased to MTV News that he was willing to do it with the other two male hotties on the show: Westwick and Chace Crawford, if need be. "I can't tell you that," he said, jokingly adding, "Hypothetically, it's all three guys."

Meanwhile, his co-star Leighton Meester didn't say much

about what we can expect, except that she approves of the show continuing to push the boundaries, especially now that Blair and the crew are in college. "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," she said. "Which is fine by me."

But leave it to Michelle Trachtenberg to open up and reveal some of the devilish details she'd like to see happen in the much-hyped, "worth waiting for" threesome. "I would imagine it's going to involve at least one boy and one girl, so ..." she said, adding with a laugh, "We'll go with Blake [Lively] and Leighton [Meester]. It would be a crazy lady threesome. It's not going to happen. I'm just messing with you. ... It's actually going to be, like, a tensome."
