This little girl must've been so excited for picture day at school -- just look at her done-up hair, pretty dress and beaming smile! Can you guess which little lady from big ol' Texas is posing in this yearbook picture?

In just a few short years after this picture was snapped, this actress-turned-singer appeared in a classic children's TV show before growing up to big and better things... namely, a starring role in a Disney sitcom.

Soon enough, she was recording albums, landing huge movie deals, and designing her own fashion line. The fact that she dated (or still is?) one of the most desirable musicians out there hasn't hurt her star power either!
