Tipsy Perry helped out of Bieber bash

Katy Perry had to be helped out of Justin Bieber's party in London in the early hours of yesterday morning.

The pair had played the Capital FM Summertime Ball in Wembley on Saturday night and after some overenthusiastic partying by the 'Firework' hitmaker at the teen heatthrob's bash at Cirque Du Soir, she had to rely on bodyguards, her PA and some of her famous friends to help her out.
