Katy Perry has near bikini malfunction at Californian waterpark

Katy Perry has near bikini malfunction at Californian waterpark Barcroft

Just a little lower and Katy Perry could have been left rather-red-faced - and exposed - as she got a drenching at a waterpark in California this weekend.

The I Kissed a Girl singer was seen laughing and giggling as she enjoyed the rides at Raging Waters in San Dimas where she headed for a bit of water-soaked shenanigans with friends.

Her two-piece black and white bikini just managed to maintain her dignity after one particularly forceful ride - although her hair wasn't so lucky.
