Katy Perry Takes A Drunken Tumble In London

Erika Brooks Adickman / June 11, 2012

When Katy Perry was finally wide awake after a long night of partying with fellow pop stars and Summertime Ball performers Justin Bieber and Jessie J, we’re going to guess that the California girl had quite the hangover. Allegedly, Rihanna’s BFF did more than overserve herself at the Biebs’ post-show bash at London’s Cirque Du Soir nightclub: She had so many drinks that part of her wasn’t working so well — her legs. According to an unnamed source that spoke with The Daily Mirror:

“By 5AM, she seemed to be having some difficulty walking and suddenly fell to the floor. She was down for a while and it took a couple of her mates to get her up. Everyone was staring and there was quite a commotion.”

See Katy as she attempts to get her bearings as she stumbles out of the club, allowing the paparazzi a greater view of her backside than she would probably like.

(Remember kids: drink responsibly. And if you do drink — don’t drink and drive — and definitely don’t wear big heels.)
