Vanessa Hudgens is unrecognizable in the trailer for 'Gimme Shelter.'

The gorgeous actress, known for glossy, lustrous black locks, hacks off her strands in the opening scene of the trailer. But she's not just cutting off her hair while telling herself she is brave and can do this. She's cutting off her past and escaping her drug addict mother.

Her character Apple has bounced from foster home to foster home and travels to find her father and herself, learning she is pregnant along the way.

The Hudge uglied herself up for the role -- the Oscars love that, just ask Charlize Theron and Hilary Swank -- which is a heavy one. She is anti-glam, with a tattoo on her neck and bitten down fingernails, as well as a lip ring. The film is based on a true story, and the trailer features a Lana Del Rey song in the form of 'Born to Die.'

In case you forgot what she looked like, a photo of the stunning former GF of Zac Efron is posted below for your gawking enjoyment. She's rocking ombre locks here, and looks amazing.
