Kristen Stewart and Dakota Fanning were spotted on the Los Angeles set of their Joan Jett biopic The Runaways on Wednesday afternoon.

K-Stew was sporting those famous leather pants, while Dakota rocked some major Cherie Currie boots. With all that makeup, they're almost unrecognizable!

What do you think Kristen is doing up on that car? She better be careful, she has a long history of eating it!
