I KNOW she's playing a badass rock star in her latest film, but is picking up a filthy habit like smoking really a part of method acting? I ADORE Kristen Stewart, and while I understand some celebs sneak a cig every once in a while, I really wish she wouldn't light up! Then again, I guess Rob wouldn't really notice when he kisses her, as he enjoys a ciggie every now and then too!
