Pro: Well, see there's this biopic about Jett's 1970's girl group The Runaways coming out next year starring "Twilight's" very own Bella (Kristen Stewart) as the Godmother of Punk. What better publicity could they ask for? Con: One of the long-standing criticisms of "American Idol" is that it favors pop music way more than rock. Even in her 50s, we have a feeling Jett is way too edgy for the "Idol" crowd. -- Brill Bundy, Zap2it Related: 'Twilight' star to play Joan JettDakota Fanning runs aways with 'The Runaways'
