My oh my, Mila!

Mila Kunis is currently making headlines for her daring love scenes with Natalie Portman in acclaimed thriller Black Swan, opening Friday -- and the star also steams it up with Justin Timberlake in the comedy Friends With Benefits, out next July.

"I adore him. He's great," Kunis, 27, said of Timberlake, 29, during a Friday appearance on The Ellen DeGeneres Show.

But the sex scenes? "It's very awkward," the actress admitted. "I mean, the truth is, we got to have very uncomfortable scenes for two weeks."

Shooting racy encounters is anything but fun, Kunis explained. "There's like 150 crew men watching and you see each other's bits and pieces. The whole thing is just wrong!"

When Ellen DeGeneres asked Kunis to elaborate on what "bits and pieces" show up in the film, the star giggled and demurred, "yeah, well, you'll see the movie!"
