Justin's busy film year

No one can say that Justin Timberlake isn't hardworking... The former boy band star has proved he's all grown up by successfully juggling an incredible schedule.

As well as keeping his fashion line William Rast going and his music career fresh (most recently lending vocals to Sheryl Crow), his next flick The Social Network is about to hit the cinemas, while filming on Bad Teacher has just wrapped - and he's currently working on next project, Friends With Benefits.

The film revolves around two pals (played by Justin and Mila Kunis) who decide to embark on a no strings attached relationship. Unsurprisingly, things start to get complicated when their feelings for each other change.

Him and the pretty Forgetting Sarah Marshall star certainly looked cute together on-set yesterday, although don't let Justin's girlfriend Jessica Biel hear us say that. To be honest, we're sure Jess had bigger issues with her boyfriend starring alongside his ex Cameron Diaz in Bad Teacher. Incredibly, we doubt Cam is too far from the Friends With Benefits set - her rumoured new boyfriend Alex Rodriguez makes an appearance in it!
