We reported last month that Garrett Hedlund was set to star in a film adaptation of a Jack Kerouac classic novel and now it seems Hedlund's wife in the film has been found. USA Today is reporting that Kristen Stewart has signed on for a role in On the Road.

The actress revealed the news while in Chicago for a taping of The Oprah Winfrey Show. Here's what she told the site.

"I am very much attached to a movie that has been trying to get made forever. Not that this is going to help it, but maybe I can just brag a little bit. I am super excited about it, too. I am about to play Marylou in On the Road. So that's a big deal."

Marylou is the wife of Garrett Hedlund's Dean Moriarty character, who travels the country with his friend Sal Paradise, who will be played by Sam Riley. Walter Salles is directing the film, which was said to start filming this summer.
