Kristen Stewart & Dakota Fanning: Runaway Ruckus

Kristen Stewart shares a laugh with costar Dakota Fanning on the set of The Runaways filming in Los Angeles on Wednesday (July 1).

Kristen, 19, and Dakota, 15, who also costar in New Moon together, were also seen jumping on cars and kicking over a couple of trash cans during the shoot.

The Runaways, a biopic on the all-teen girl rock band formed in Hollywood in the 70s, opens in theaters next year.
