The stars came out for the big Hollywood premiere of Cirque du Soleil's "Iris" at the Kodak Theater on Sunday, and Vanessa Hudgens was sweet enough to bring her sis along to opening night.

The Beastly star looked hippie-chic in a full length maxi dress with feather motif, paired with a long white scarf and platform shoes, while little sis Stella opted for a much shorter dress and turquoise head scarf.

In other news, the former High School Musical star is gearing up to appear alongside Nicolas Cage and John Cusack in the upcoming film, The Frozen Ground.

The film, based on actual events, is set to hit theaters December 2012.
