Demi Lovato's 20th Birthday: A Look Back At Her Style Evolution (PHOTOS)
Celebuzz is wishing Demi Lovato a very happy birthday today, as the actress-singer hits the big 2-0.
In just a short amount of time, Lovato has blossomed from Disney princess to true fashion icon, donning looks that are both fashion-forward and daring.
She may have had a rough adolescence, but the X-Factor judge is finally putting those teenage years behind her as she steps into her early twenties.
Celebuzz is celebrating her new new adulthood with a look back at the star's style evolution.
Lovato has transformed her hair several times over the years -- from dark brown tresses to blonde hair with crayon-colored tips.
As for her apparel, the "Give Your Heart a Break" singer first took on the musical scene by donning feminine frocks, but has amped up her looks to rocker-chic in the last couple of years. This has included everything from studs, to bold lips and, yes, leather.
