Justin Timberlake turns his back on naked scenes

Justin Timberlake will not go nude for a movie role again, he has claimed. The singer and The Social Network actor appears in the forthcoming Friends With Benefits opposite Black Swan star Mila Kunis.

The film required him to film sex scenes with Kunis wearing only a modesty sock. Now he has told Vanity Fair he does not plan on repeating the experience.

He said: "It was fun, but I can’t say I'm going to be butt-naked in a movie again. I only did it because I'm young now, and everything's where it's supposed to be. I figured this is the time, before gravity gets the best of me."

Kunis added that she found filming sex scenes with Timberlake to be strenuous. She said: "It's always uncomfortable to do those scenes... You have to be in these crazy positions for 12 to 16 hours. I'll never forget when Justin had to be on top of me with his right hand on my left pasty [nipple cover] and his left hand on my right pasty.

"My feet were getting numb, and I think his hands were giving out on him. It was a workout."

Friends With Benefits opens in the UK on September 2.
