After seeing Kristen Stewart live every girl's dream on screen with Robert Pattinson, we can officially say we're jealous of her. And now we're super jealous because according to The Hollywood Reporter, Kristen has signed on to play Joan Jett in a biopic about her 1970s girl band, The Runaways. The movie will follow Joan as a teenager and explore The Runaways' success with hits like "Cherry Bomb" and their eventual breakup over management and money issues. Production is set to start next year and will have to revolve around Kristen's commitment to the Twilight sequels since, according to People, New Moon is expected to shoot sometime in early 2009. That's so soon! Are you excited for the sequels or are you over Twilight mania? Tell us below!
