"I'm, like, vibrating," grinned Stewart when we asked about "The RUNAWAYS," a 1970's-era flick about the influential all-girl rock band fronted by Jett and Lita Ford. "I'm just so excited about that movie."

"I'm really, exceedingly, more excited than normal," she laughed. Directed by Floria Sigismondi, the flick will tell the story of the teenage band who were brought together and thrown into leather and lace, performing such sneer-filled songs as "Cherry Bomb." Although they barely lasted four years and only put out a handful of albums, the band was able to overcome their sleazy "jailbait" gimmick to become an influential punk band that would eventually help birth such successors as The Breeders, L7 and The Donnas.

JOAN JETT herself has signed on to be the film's executive producer, and Stewart revealed to us that not only is she currently hard at work picking up old guitar riffs, but she's also been spending quality time with the durable rock goddess herself.

"Yeah, I spent New Year's with her," Kristen said of her new buddy JOAN JETT. "I spent, like hours, just talking to her."

"The RUNAWAYS" hopes to begin filming near the end of 2009, and will follow the all-girl band from their mid-70's formation to their late-70's collapse. After their music Ð typically songs about sex, booze and life on the streets Ð died down, Jett (born Joan Larkin) went on to become one of the most popular female rockers of the early Eighties. Backed by the BLACKHEARTS, her attitude-filled hits "I Love Rock Ôn' Roll," "Crimson and Clover" and "Do You Wanna Touch Me (Oh Yeah)" took her to the top of the charts and launched Jett on a successful career that still has her recording albums and touring extensively while she proudly maintains her punk attitude at age 48.

"It's been great," KStew said of her recent tutelage by JOAN JETT.
