These Celebrities Don't Actually Use Their Real Names

Bruno Mars

Mars was born Peter Gene Hernandez, though the "Grenade" singer has been Bruno his entire life. He was given the nickname as a toddler when his parents said he looked like wrestler Bruno Sammartino. However, he also thought his given last name would force him into the niche of Latin music, and that wasn't the angle he wanted to pursue.
