During a trip to the San Dimas Raging Waters water park, to the delight of visitors, Katy Perry put on an unexpected show yesterday (August 12, 2012).

The singer’s bikini bottoms dropped as she was getting out of the water after venturing down a waterslide, and her bikini top almost fell off as well.

Katy’s new boyfriend John Mayer was busy having fun with friends in Malibu, but they were spotted together leaving a house party in Los Feliz, CA this past weekend. 

A source told E! News Perry and Mayer have been laying low at the Mayer’s home, having “sleepovers” together.

I’m sure they’re just braiding each other’s hair.
