Beach blunder for Vanessa Hudgens

VANESSA Hudgens was taken by surprise as she soaked up the sun in Hawaii – when she suddenly found herself holding up her swimwear.

The High School Musical actress was relaxing on the beach when her biniki's clasp suddenly flew open.

Fortunately the 23-year-old star was able to catch it in time — then found herself unable to do it up without revealing more.

But with a sun shade to hand, it wasn't long before she was fully dressed and back to topping up her tan.

Vanessa has barely been off the sands in recent days, usually with boyfriend Austin Butler.The pair have been together since last September, but still seem to be enjoying their honeymoon period.

The young lovers have been spending most of their time canoodling on the beach — though they did find time for a quick kayaking session.
