2. Selena Gomez
"Wild" to Selena Gomez typically means making out with beau Justin Bieber at awards shows. However, she let loose on the set of Spring Breakers this year. The sweet starlet donned a bikini for most of the film, in which she plays a girl who drinks from a brown bag and gets arrested for robbing a restaurant! She said the role was unlike anything she's ever done. "That's why I took so many pictures! I was like ‘Why am I so excited to be arrested?' But, I was super excited," she said.
