The Justin Timberlake and Mila Kunis romantic comedy Friends With Benefits drunk dials movie theaters today, and a lot of people have been on the fence about whether or not it’s a flat out ripoff of the Ashton Kutcher/Natalie Portman comedy, No Strings Attached. And the correct answer is… who cares, it’s Mila Kunis.

Alas, Mila has shared some less than stellar news with Ryan Seacrest, in regards to her hot and heavy scenes in FWB. It turns out that we get to see some skin of the buttocks variety from the GQ cover girl, and that’s clearly great news. But whose skin is it? WHO, DAMN IT!

“These young ladies came in,” she explained. “They were in a casting room and I was there, the director and the casting director and my makeup artist were there. And these lovely women had to show us their derrieres and we chose the one that resembled my body the most without looking like it’s fake.”

But, Kunis didn’t require body doubles for all of the revealing scenes. So, what caused the posterior shyness?

“I showed side-boob, and I figured I can’t just give away everything all at once,” she joked. “I gotta let it all out in little pieces here and there.” (Via Hollywood Reporter)

Damn, this is a tough one. On one hand, she’s willing to give us side boob. On the other hand, we’re seeing someone else’s butt instead. I say we let it slide this time, but if it’s not her tush in the next 10 movies, then we’re going to have some serious problems.
