4. Britney Spears, ‘Criminal’

The video for one of Britney's lesser hits, 'Criminal,' features the singer as arm candy for a well-to-do jerk. When he starts getting handsy with her, a scruffy criminal (played by her soon-to-be husband Jason Trawick) saves the day and Brit flees with her rescuer. We know the guy is no good because he has a motorcycle, a giant tribal tattoo, and a gun, but Britney is drawn to his lifestyle. Before you know it, she's committing robberies with him. The pair go down in a hail of bullets -- the perfect ending to an epic heist saga.
