Guess Who This Posin' Princess Turned Into!

Before this baby with bed head was starring on television, she was just another princess posing for the camera in Sofia, Bulgaria.

This brunette baby rose to fame on a popular teen drama named after the fictional high school she attended with an actor and hip-hop artist who started from the bottom. She quickly moved on to become the beloved lead in a supernatural series -- adapted from a popular book franchise -- filled with blood-thirsty villains.

Now, this famous female has made appearances on the big screen ... including the film "The Perks Of Being A Wallflower."
