Watch out, Rob Pattinson! Kristen Stewart's found a new love interest . . . on the big screen, at least.

The first film stills have been released for On the Road, the upcoming film adaptation of writer Jack Kerouac's classic Beat Generation tome.

In the flick, Stewart, 21, plays Marylou Moriarty, the on-again, off-again wife of Dean Moriarty (based on real-life Beat icon Neal Cassady), played by hunky actor Garrett Hedlund.

Stewart recently told Vogue she was "crying my head off" shooting the film. "I didn't want to leave."

Do Stewart and Tron: Legacy star Hedlund, 26, have any, er, intimate scenes in the flick? "There's a few," the actor told E! News.

In real life, Hedlund recently made waves at a Golden Globes after party -- where he and Country Strong costar Leighton Meester were "inseparable" according to one witness. "Garrett wrapped his arm around her...She wrapped her arm completely around his neck and pulls him for a quick peck on the lips."
