Hollywoods Hottest Stars Shed Their Aliases

#36. Bruno Mars

Real Name: Peter Gene Hernandez

Peter Gene Hernandez was a name that didn't stick for long. Once his family noticed that their toddler looked like wrestler Bruno Sammartino, they started calling him Bruno, too. He went by Bruno Hernandez for a while, but Harper's Bazaar reports that music industry execs tried pigeonholing him as a Latin artist. So, he swapped out his last name, too Mars fit the bill.
