"Black Swan's" Mila Kunis — whom The Advocate asked about off-screen jealousy before she split from longtime boyfriend Macaulay Culkin — recalls nude scenes with Justin Timberlake and the last time she simulated oral sex with a woman.

ADVOCATE: Your next film, "Friends with Benefits," also looks pretty racy. In the trailer, you’re shown standing in front of a naked Justin Timberlake and sizing up his goods. Set the scene: What were you really looking at?

KUNIS: We had two weeks worth of sex scenes to shoot. Justin would just wear a sock that covered his frontal parts, so yeah, I could pretty much see everything. And I had tiny nipple pasties and a little pasty on my hoohah. We couldn’t have been more uncomfortable in the beginning, but by the fourteenth day, we’d just drop our robes, like, “Hey, how’s it goin’?”

ADV: Does your boyfriend, Macaulay Culkin [with whom she has since broken up], ever get jealous of that kind of thing?

MK: Well, when you sign up for a movie called Friends with Benefits, you kind of know what you’re getting yourself into. But it’s work. It’s all very strategic, because there are 150 crew members trying to light you and make sure no one can see your pasties. And Justin couldn’t have been more of a gentleman, because it can be very awkward.

ADV: In another [Family Guy] episode, Meg pretends to be a “super huge mega-lesbian” to infiltrate her school’s lesbian club because being gay makes her cooler.

MK: Being gay is cool. I just wish gay kids realized that earlier in their lives.

ADV: [Inside the Actors Studio host James] Lipton also didn’t get to ask you the Proust questionnaire, as made famous by Bernard Pivot. So what’s your favorite curse word?

F**k. It’s a good, strong word.
