So, what's the real deal with this former Elvis impersonator?
Check out the five things to know about Bruno Mars!
5) Bruno's real name is Gene Bayot Hernandez, but the singer's dad gave him the nickname "Bruno" when he was a kid because of his resemblance to professional wrestler Bruno Sammartino. When Bruno pursued a singing career and felt like label execs were trying to pigeonhole him to Latin music, he changed his name to Bruno, and adopted the last name Mars, according to GQ. Why Mars? "Because I'm out of this world," Bruno told the New York Daily News.
4) At the age of four, Bruno joined his family's variety show in Hawaii as an Elvis impersonator, and went on to play one in the 1992 comedy Honeymoon in Vegas. He also wrote a song for his mother, Bernadette Hernandez, when he was four called "I Love You Mom." She passed away from a brain aneurysm June 1. Following her death, Bruno thanked fans for their support, tweeting, "I'll be back on my feet again soon. That's what mom wants. She told me."
3) Not only is he one heck of a singer, but he also plays the drums, keyboard, bass and guitar.
2) Bruno also shines when it comes to songwriting. After struggling to make it as an artist, he started writing and producing songs with songwriter Phillip Lawrence, according to People, and it catapulted his career. He wrote Cee Lo Green's "F--- You," Travie McCoy's "Billionaire" and Flo Rida's "Right 'Round," among other hit songs.
1) He has been nominated for 14 Grammy awards to date and won one for Best Male Pop Vocal Performance in 2011 for "Just the Way You Are." He has also been nominated for 20 Billboard Music Awards and won one for Top Radio Song in 2011 for "Just the Way You Are."
