Kristen Stewart Keeps Rockin' Away

Back out in her rocker chick ensemble, Kristen Stewart was spotted on the set of "The Runaways" in Los Angeles on Wednesday afternoon (June 24).

Getting a late start to the day, the Bella Swan actress petted a pooch as she made her way inside to get ready for another night's filming of her Joan Jett rock star role.

Meanwhile, the day’s film outing comes amidst rumors that Kristen is a bit jealous of her "Twilight" co-star Robert Pattinson and his "Remember Me" co-star Emilie de Ravin's smooch scenes.

An insider alleges to OK! magazine, “She knows screen kisses are part of Rob’s job, but it doesn’t make things easier, seeing sexy photos of him and Emilie in full lip-lock. Kristen saw a photo of them kissing and flipped out. It’s made her nervous and more determined to visit him in New York… It’s clear Rob and Emilie have a lot of movie chemistry.”
