Demi Lovato isn't afraid to get wild!

The Disney star is all grown up and took the stage on Wednesday night at Los Angeles' famed Greek Theatre looking ready to rock and Breaking Celebrity News has the photos.

Demi, 19, sported a short leather skirt, a studded bustier, a cropped leather jacket and pink color in her hair.

Earlier this year the X Factor judge admitted to trashing dressing rooms "just for the hell of it" because she was "bored" while on tour.
