Vanessa Hudgens hated acting underwater in Journey 2

Vanessa Hudgens battled her worst fears on the set of new movie Journey 2: The Mysterious Island - she hates acting underwater.

The former High School Musical star had to shoot swimming scenes in the new family action film and she admits they almost drove her mad.

She says, "I have such a pet peeve, I hate getting my face wet and fully submersing myself under the water, let alone opening my eyes and acting underwater. It aggravates me; the feeling of it."

And she also found the bugs on the Hawaiian location tough to deal with: "There are centipedes crawling around that were so disgusting and massive with all their little legs. They freaked me out."
