"Twilight" star Kristen Stewart has signed on to join Sam Riley and Garrett Hedlund in a new movie adaptation of Jack Kerouac's iconic novel "On The Road."

She'll play Dean Moriarty's wife Marylou in the Walter Salles film.

The actress recently told Elle magazine how difficult it is to deal with fame, fans, and the paparazzi. She explained, "It's insane! Once somebody finds out, you have to get the hell out of wherever you are. People freak out. And the photographers, they're vicious. They're mean. They're like thugs. I don't event want to drive around by myself anymore. It's fucking dangerous."
