Miranda Lambert is a bit of a Stepford Wife in her 'Mama's Broken Heart' video. She's quite the actress, showing off her crazy side with reckless abandon -- but she makes nutty look good. Her character pops Rx pills, which she washes down with a glass of scotch. She's got a fancy house and lots of swanky things, but none of it's making her happy. Despite that heavy theme, the video is fun and Lambert is a hoot, chewing the scenery as she comes undone.
