It's no secret that Kristen Stewart has become very, very famous over the past year. It's also no secret that she takes her craft very seriously, respects a lot of artists who have come before her and holds a special place in her heart for Joan Jett.

At Monday's (November 16) "New Moon" premiere, the legendary rocker was a special guest on the red carpet, walking just a few feet ahead of the A-list actress who has spent the past few months sharing her short, spiky haircut for "The Runaways," an upcoming film about Jett's all-girl '70s punk band. 
Stewart told us the film is going to aim for a Sundance premiere in January, and Jett revealed much more about the pair's friendship and whether KStew will be performing her own music in the flick.
