Katy Perry suffers water park wardrobe malfunction

Katy Perry was left red-faced during a trip to a water park over the weekend (11-12Aug12) when her bikini bottoms fell down, exposing her bare butt to amazed onlookers.

The I Kissed a Girl singer took a trip to Raging Waters in San Dimas, California and was photographed enjoying the amusements with a group of friends.

However, Perry suffered a major embarrassment when she rode a body board down a water slide and her swimwear slipped down in front of a large crowd of fellow revellers.

Photographs of the incident show a water park staff member rushing to cover Perry's bare butt with the board as she struggles to pull her bikini bottoms up.
