Former High School Musical star Vanessa Hudgens showed her support for longtime boyfriend Zac Efron last night by attending the premiere of his latest film, Charlie St. Cloud. Hudgens was lovely as ever in a soft cream-colored Reem Acra dress with a jeweled neckline.

Hudgens augmented the look with the typical Hollywood accessories: metallic Jimmy Choo sandals, a hard box clutch and several sparkly bangles. But there was one more interesting accent: traditional Indian Henna designs on her left hand. The flower-based dye is often used to celebrate weddings, holidays and births. What do you think Hudgens is celebrating?
