Believe it or not, it was just three years ago when Bruno Mars first showed up on Billboard's Hot 100 chart with B.O.B.'s song "Nothin' On You." Since then, he's been cranking out the hits. His latest album, "Unorthodox Jukebox," was his first to hit #1 and it has produced a bunch of hit singles. Congrats, Bruno!
