Katy Perry made quite the splash at a Southern California summer hot spot, Raging Waters, over the weekend. Trying to beat the heat, the Firework singer, hit up the popular San Dimas waterpark, and if her fame wasn't enough to draw a crowd, Katy suffered a MAJOR wardrobe malfunction. Exciting one of the waterpark's wild rides, Katy lost her bikini bottom, exposing her bare bum for everyone to see!

In the pics, which can be seen here, Katy almost completely loses her bikini bottoms, as well as her top... giving bystanders a glimpse of her entire rear-end and a partial boob shot! Other than this small mishap, Katy appeared to be enjoying her fun day in the sun and water, laughing and smiling with her entourage.

Noticeably absent from the outing, Katy's new BFF, John Mayer! The duo have been spotted spending A LOT of time together lately and rumors of a romance have been circulating.
