Nick Cannon aka "Mr. Carey"

After getting married to pop star Mariah Carey, Nick Cannon went on to tattoo her name on his back, and now has taken on the name Mr. Carey.

Cannon isn't acting as her bodyguard in taking on the new last name. "I make fun of me all the time," he told In Touch Weekly. "I'm like, 'call me Mr. Carey, who cares?'"

His next career move . . . working as director for his wife's new video, "My Love."
