THIS MUSIC INDUSTRY 'TREASURE' IS CELEBRATING A HUGE MILESTONE

Bruno Mars has earned a reputation for creating music's catchiest tunes and owning a strong set of pipes.

The 'Finesse' hit-maker turns 40 on October 8 - and that's just one more reason to celebrate, amid a career brimming with accolades, milestones and millions of adoring fans.

Mars told CNBC Make It. "So if I'm writing a song, I have to be sure that this is the best I can do, deep down in my soul, and that I didn't take any short cuts. I have to really believe in what I'm doing for it to work."

Hard work and honesty was ingrained into Mars from a young age. At just two years old, the 'Marry You' singer - born Peter Gene Hernandez - got his start on the stage as the world's youngest Elvis impersonator in his home state of Hawaii.
