Singer-turned-actor Justin Timberlake has ruled out stripping down for another movie role, insisting his upcoming nude scene will be his last.

The Social Network star bares all with Mila Kunis in new film Friends With Benefits, but he doesn't plan on ever repeating the experience.

He tells Vanity Fair, "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."

Friends With Benefits is set to hit theatres on July 22nd.
