It seems as though 2010 is going to be the year that Kristen Stewart looses all her inhibitions when it comes to acting.

Not only will the actress be getting up, close and personal with Robert Pattinson on Esmee Island in the Twilight Saga, but her role in her new flick, On The Road may ask for her to take part in a threesome.

According to Celebuzz, Kristen who plays MaryLou in the movie adaptation of Jack Kerouac's novel is a bit of a wild child.

Life & Style report: “Her character,16-year-old Marylou, has a threesome with a couple of hotties, asks to watch two people have sex and brags about loving to perform oral sex.”

Ooo-er...we wonder what rumoured beau Robert Pattinson will say.....
