Natalie Maines NMAINES080807_01.jpgLooks like the incarcerated celebutantes club's going to be getting a new member - but would you believe that it's Natalie Maines? Actually, you'd be right if you didn't buy the story - Natalie's only going to prison as part of Stealing Cars, a movie in which she's been cast as a nurse. Still - we're guessing she'll be pining for some wide open spaces by the time shooting wraps up!
