Kristen Stewart is MAD for some sexy time. And we don't just mean with her movie's directors (which, let's face it, she also likes), we mean on screen. Yes, the On The Road star has revealed that she was really keen to do the sex scenes in the Jack Kerouac adaptation as she loves "pushing" and "scaring" herself.

Chatting to Contactmusic, the now 22 year old star who got the part of Marylou when she was just 16 said: "I was terrified of this part. I knew I was going to play Marylou since I was 16. And thank God I got to grow up a little bit, because I was a much younger 16 year old than LuAnne [Henderson, who the character is based on]. We made the movie when I was 20, the perfect point... But I love pushing, I love scaring myself. I really wanted to do the sex scenes. As long as you're being really honest there's nothing ever to be ashamed of."

Let's just hear that one more time; 'As long as you're being really honest there's nothing ever to be ashamed of.' Really Kristen, is that your life motto, eh?

Moving on. Now we weren't too fond of the movie ourselves (check out our review here) but it does boast some exposing scenes involving a starkers K-Stew, should that be your thing. Among other racy shenanigans, On The Road also features a threesome.
