Hudgens in tears after workouts

Vanessa Hudgens has revealed she was in tears after training with Navy Seals for her latest movie role.

The High School Musical star worked out with Seals for several months to prepare for action flick Sucker Punch and told People the gruelling sessions were a challenge.

"I was bawling my eyes out because they push you so hard," said the 21-year-old. She went on: "It was the most intense thing that anyone could ever do."

However, Vanessa, who is dating her HSM co-star Zac Efron, said the training was ultimately "empowering".
