JT talks sex scene fun with Mila

Justin Timberlake has spoken out about filming sex scenes with his Friends With Benefits co-star Mila Kunis.

Talking to E!, Justin admitted that shooting sex scenes with the Black Swan star was "an easy thing to do... I think I could speak for all the men in the world when I say that's the easy part".

Filmed in New York City, the romantic comedy tells the story of two professionals, Dylan (Timberlake) and Jamie (Kunis) that, being too busy for a serious relationship, decide to get together for a no strings attached fling, but things start to spiral out of control when Dylan falls for Jamie.

Set for a September 2011 release in the UK, Friends With Benefits is the first of three up-and-coming films starring Justin, who said of the movie: "Honestly, it was a golden opportunity to find a lot of humour that maybe hasn't been portrayed in film - in bed and on film... we found a lot of jokes. We had a two-week block where we had interiors every day and it was all sex jokes."
