Wow. If you know who this artist is, than you know how shocking it is to see her without her normal stage makeup and crazy-colored and styled locks.

Just a few years back, this pop diva struck a pose in her New York City high school for her yearbook. Although she hadn't skyrocketed to fame yet, she already had a cameo role on a hugely popular TV show. Even though she is one of the most-liked people in the music biz today, this young lady was a victim of bullying back in high school, and she still feels strongly about this issue today. Nowadays, we bet her high school haters are kicking themselves, since this 20-something singer has eaten her way into the hearts of fans all over the globe and keeps busy making millions.
