Bruno Mars is the epitome of what a true entertainer should be. Born in an artistic family on the exotic island of Hawaii, Mars, whose real name is Peter Hernandez, is a talented jack-of-all-trades kind of singer, whose showmanship celebrates the height of the old 1970s and 1980s R&B. Up to this writing, the Silk Sonic crooner is a proud recipient of 15 Grammy Award wins thanks to his various albums and collaborations throughout the years, and he's not showing any sign of slowing down.

Before he was Bruno Mars, young Peter Hernandez began his show business at the age of two when he became the world's youngest Elvis impersonator. Inspired by his uncle who was also an Elvis impersonator, he slowly made his way to local stardom for performing with his family band called The Love Notes, specializing in doo-wop and musics from the '50s. He told Rolling Stones in a 2013 cover story, "I would look forward to getting out of school. Just looking at the clock, waiting for it to hit 2:15."

6 Bruno Mars Was A Celebrity Impersonation In High School

While in high school, Bruno Mars' popularity skyrocketed to the point where he would perform gigs as Michael Jackson and other artists' impersonations, making $75 for each show. A natural heartbreaker, he was also popular with the ladies and even dated his back-up singer when he was 16.

"After that, I walked around the halls like I was (Frank) Sinatra," he told Rolling Stone about his rendition of Ginuwine’s “Pony” in that show where teachers yelled at him for singing along the word "horny." He added, "I was like, ‘OK. I’m not just an impersonator. I can also impersonate Ginuwine!'"

5 Bruno Mars' First Attempt At A Record Deal

Fresh off the boat after graduating from high school, 17-year-old Bruno Mars relocated to Los Angeles, California, to take his singing career seriously. Mike Lynn, who was the head of A&R at Dr. Dre's Aftermath Entertainment at the moment, told him to come after Mars' sister gave him his demo tape. He adopted the stage name Bruno Mars to further avoid being stereotyped as a Latino singer. Shortly after, he signed to Motown Records, but the deal went sour, and he eventually got dropped from the label not a year after.

"I might have cried. I might have shed some tears, he recalled, adding, "You definitely have those nights where you feel a little insecure, but I didn't want to give up."

They eventually formed a songwriting and producing collective called The Smeezingtons and are responsible for some of the most iconic hits of the late 2000s and early 2010s, including B.o.B's "Nothin' on You," CeeLo Green's "F You," Flo Rida's Kesha-featuring "Right Round," and more.
