Sometimes when you see Nick Cannon next to Mariah Carey, you think, "What does he do again?" But before he was a famous husband, he was an actor/musician who rose to hip-hop fame with a remake of Will Smith's "Parents Just Don't Understand" and had a self-titled album out in 2003. He released a few more singles in 2005 before packing it in for husbandhood (and acting). Last year, Cannon and Carey had fraternal twins, Monroe and Moroccan, who will undoubtedly become huge (but not bigger than Mariah) stars. Mariah wouldn't have it any other way.
