You may know Bruno Mars as a mutlitalented performer [1] and a brilliant songwriter [2], but do you know his real name? It's very common for celebrities to go by stage names [3] that completely differ from the monikers they were given at birth, and Bruno is one of those stars. Born Peter Gene Hernandez, the 31-year-old singer landed the nickname Bruno [4] as a toddler because he resembled famous wrestler Bruno Sammartino. While seeking a recording contract at the age of 17 in LA, Bruno acquired the last name Mars because of the responses he would receive: "Your last name's Hernandez, maybe you should do this Latin music, this Spanish music . . . Enrique's so hot right now." Maybe he wanted to sound like he was from another planet?
