Vanessa Hudgens's 'Intense' New Exercise Partners: Navy Seals

Forget a personal trainer.While preparing for an upcoming film role, Vanessa Hudgens recently adopted several unorthodox exercise partners – partners who had her in tears by the end of the workout. "I trained with Navy Seals for five months," she told PEOPLE at Las Vegas’s ShoWest movie convention. "It was the most intense thing that anyone could ever do."Breaking from her typical tween roles, Hudgens, 21, will star in the 2011 movie Sucker Punch, an action flick set in the 1950s."I walk around with the biggest guns you have ever seen," she said.
