Yesterday as Katy Perry enjoyed a trip to Raging Waters in San Dimas she showed off a little bit too much of her enviable bikini body as she took to a ride in a two-piece.

The singer who is known for her love of amusement parks found herself overexposed when her bottoms slipped down as she went down a water slide.

But true to form, Katy simply laughed the incident off and opted for another go on the ride as fans cheered her on.

Malfunction: Katy surprisingly bountiful alabaster bottom was on full display for all to see

With rumoured new love John Mayer absent from festivities, Katy Perry had no one to impress.

As a result, the usually-immaculate popstar was seen with drenched hair dripping all over her face during her eventful day to the Californian waterpark.

However, despite being lax about her make-up free appearance, Katy did showcase an enviable bikini body that no doubt caught singer/songwriter Mayer’s beady eye.

Apprehensive: Katy Perry looked somewhat nervous as she prepared to hit the water slide in San Dimas, California…  and for good reason

The bikini that got away: The 27-year-old found herself a little overexposed as she came up from the water

Exposed: Katy’s friend rushed to help her but it was a bit too late to spare her blushes

The I Kissed A Girl songbird appeared to be having a blast as she was seen giggling and waving as she hung out with friends.

The 27-year-old almost had another mishap when she nearly spilled out of her black and white halterneck two-piece, perhaps with the bra top having slipped while she was on a slide.

She showed off a trim figure while looking a little sunburned on her stomach and chest.

High spirits: Katy offered a wave, having previously spent the night partying with rumoured beau John Mayer

Katy is believed to be dating John after a series of sightings with the 34-year-old, including last night.

The pair were seen accompanying one another to a house party in Los Angeles, and then leaving the Los Feliz home together.

Katy’s divorce from Russell Brand was made official last month, with the Englishman – who performed at tonight’s Olympic closing ceremony – having moved on with new love Isabella Brewster.
