Vanessa Hudgens Has "Will" Power

Vanessa Hudgens chats away on her iPhone on the Texas set of her latest movie, Will.

The film centers on a high school outcast and a popular girl who form an unlikely bond through their shared love of music. Assembling a like-minded crew of misfits, the friends form a rock group and perform in the battle of the bands competition at their school.

Earlier this week, for her character, the 18-year-old High School Musical star was seen performing on stage with a Gibson Flying V guitar.

Rocker chick Vanessa!
