Vanessa Hudgens and Austin Butler: Hakkasan Night Out in Vegas

Christening a new Sin City hotspot, Vanessa Hudgens and Austin Butler celebrated the opening of Hakkasan Las Vegas at the MGM Grand on Saturday (April 27).

The "Spring Breakers" star sported a very short, sleeveless, and sparkling black dress with pointy heels as she clung to her "Carrie Diaries" beau.

On Friday, the 24-year-old actress took time out from her busy schedule to hang out with her younger sister, Stella.

Posting a pic of them striking poses against a bathroom wall in midriff-baring outfits, Vanessa captioned it, "yin yang sisters."
