Kate HudsonKate Hudson gets raunchy with Dane Cook. On film.

Like Jessica Alba before her, cutie-pie Kate Hudson is teaming up with Dane Cook to push the boundaries of her PG-rated career in 'My Best Friend's Girl.'

Cook is a professional d*** in the racy rom-com. No, he's not a man-whore, he's a guy who gets paid to be offensive to girls so they'll go back to their boyfriends. Needless to say, he's really, really good at his job.

Jason Biggs is the titular "best friend." Heh, we said "titular." And if you think that's juvenile, just wait till you see the exclusive R-rated trailer for 'My Best Friend's Girl.'
