On a recent episode of "Gossip Girl," Chuck Bass kissed a boy, but that's not the only provocative story line set to take place this season. There's still that much talked-about threesome. In her usual sassy way, Michelle Trachtenberg revealed, well, that she can't actually reveal anything about what will happen when it all goes down.

"Ah, yeah, it's me, myself and I, and we get busy," Georgina Sparks herself joked to MTV News. "It's going to be, like, in split screens. So it's going to be like Michelle, Michelle, Michelle, like, 'What body part is that?' But it's all mine."

All joking aside, she went on to divulge that the scene would be "worth waiting for," and pondered the setup: "I would imagine it's going to involve at least one boy and one girl, so..."

Even though she wasn't able to leak any spoilers, Trachtenberg was willing to fess up about who she'd like to see get busy. "Um, all of them! You can't possibly make me pick!" she said. "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."

Trachtenberg also gushed about the news that Lady Gaga will be making a cameo in a future episode. Unfortunately, all the actress could share about the appearance was that she missed it.

"She performed on the show, so that's pretty fantastic 'cause I'm a huge Gaga fan. I was not there. ... I missed out on Gaga," she said, adding that she doesn't know when the singer's episode will air. "I just don't know things like [airdates]. We just show up and hope we look somewhat glowy."
