Biggest accomplishment this year: Co-starring in the successful indie film Spring Breakers
Like it or not, Selena Gomez is one of the most famous and successful young female entertainers today. Her high-profile relationship with fellow youngster Justin Bieber has made the pair tabloid stars for the better part of two and a half years even after their reported January 2013 breakup. Gomez has done just fine on her own, and recently released "Come & Get It," the first single off her new album Stars Dance, scheduled to drop this summer. She also made waves for her role in the controversial film Spring Breakers, in which she plays the one "good girl" in the entire movie.
