Mila Kunis Enjoying Holyday With Her BoyFriend: It's a position thousands of Justin Timberlake fans would give their right arm to be in. But Mila Kunis took cosying up to the SexyBack singer in her stride as they filmed scenes for their new movie, Friends With Benefits, in Malibu yesterday. Timberlake was spotted giving Kunis, 27, a boost over a beachside porch as she held on tight to the singer-turned-actor's gym-honed arms.

The pair then ran down to the sea before Timberlake tried to impress Kunis by showing off his throwing arm. They were only acting, but their obvious on-screen chemistry might hit a nerve with their respective other halves. Timberlake, 29, has been dating actress Jessica Biel for three years, although recent reports have indicated their romance may be on the rocks, while Kunis has been dating former child star Macaulay Culkin since 2002.
Friends With Benefits also stars Woody Harrelson and Zombieland star Emma Stone, and follows the lives of two friends as they become romantically involved. Kunis is best known for her role alongside Brit comic Russell Brand in the 2008 comedy Forgetting Sarah Marshall, but will appear in the Darren Aronofsky thriller, Black Swan, later this year. The hotly-anticipated film co-stars Natalie Portman and Winona Ryder.Timberlake has steadily been building up his acting CV since making his big screen debut in Alpha Dog in 2007, but the fruit of his acting endeavours have been a mixed bag. He was praised for his role in crime biopic Alpha Dog, while the Mike Myers' vehicle, The Love Guru, was a box office flop. It won three Golden Raspberries - the spoof awards given out to the worst Hollywood films of the year - in 2009.
