Actress Liv Tyler was given the nickname 'Action Pants' on the set of her new movie THE Incredible Hulk after a wardrobe malfunction left her flashing her bare butt at crew members.
The 30-year-old, who plays Betty Ross in the comic-book movie, fears footage of the accident will eventually emerge online.
She explains, "I wore the same outfit for the whole movie, these really tight pants. We did this scene where a helicopter crashes and I'm thrown out. When the director said cut, I stepped off set and suddenly felt this breeze.
"I reached around and there was a rip a foot and a half long. You could see g-string poking out and white butt cheek. The camera-man, after that, he called me Action Pants. It was a very humbling experience."
