Spending the day on the set of her new movie, Kristen Stewart was spotted plugging away on “The Runaways” in Los Angeles on Sunday (July 19).

Joined by co-star Dakota Fanning and fellow band characters, all of the members had shirts on showing their names as they strolled about the set.

Directed by Floria Sigismondi, the rocker chick flick is described as “a coming-of-age biopic about ’70s teenage band The Runaways.”

Making sure everything goes according to plan, singer Joan Jett was also on-hand for the day’s filming – as she’s been a mainstay on the set throughout production.
