Oh K. Stew, we love love looooove you, but every time we see you smoking a ciggie, we cringe just a little bit. Maybe once The Runaways wraps and you're not playing a rock star anymore, you'll ditch the smokes? We snapped the actress on set yesterday, and while she was looking a little down (no to mention dressed down), she still looked stunning!

What's she going to do with her hair after this flick is done shooting? Keep it black or go for some highlights?
