When it comes to teen celebrities, fans know Demi Lovato is the real deal. She's opened up about the struggles she's faced in the past while always staying upbeat and positive about the future, all while churning out one chart-topping song after another. Her inspirational message and incredible talent has brought Demi to the height of her careers, and today, Demi really has a lot to celebrate -- she's turning 20!

Earlier this year, Demi told Self Magazine: "When I’m confident enough to show myself without makeup on, that’s when I feel my most confident."
