Well Hello Katy Perry's Ass!!

While out having fun on Sunday at a water park in California, Katy was caught attempting to get out of a pool when her bikini bottom fell down and her top almost came off, all at the same time! Of course there were paps around to catch the whole thing on camera and that deserves a pat on the ass. (OK, that was a pun.) But you do have to admit we are pretty funny... just don't laugh your ass off. Ha!
