Vanessa Hudgens isn't a squeaky-clean star any longer, as the 'High School Musical' star is playing a pregnant teen in the new film 'Gimme Shelter'.
Hudgens will feature in the film along with Rosario Dawson, who plays the role of a drug-addicted mom, the New York Post reported.
The 25-year-old prepared for the role by cutting off her locks and living in a shelter with homeless mothers for weeks.
