Notable Role: Brit in Spring Breakers (2012)

She's already made a name for herself with the teen fans of her ABC Family show, Pretty Little Liars, but now she's moving on to a more mature audience—one that won't throw a fit when they see her dancing with a rifle and encouraging Disney stars to smoke out of a bong. Dressed in pink unicorn-patched ski masks and neon bikinis basically the whole film, the 23-year-old California native certainly leaves her family-friendly image behind in the heart-pounding party movie of the year, Spring Breakers.
