It’s safe to say Katy Perry is having fun during her stay in London. And she well and truly let her purple hair down after performing at the Capital FM Summertime Ball this weekend.
Along with pals Justin Bieber, Jessie J and her current love interest Florence + The Machine guitarist Rob Ackroyd, Katy partied until 5am at Cirque du Soi in London. And Katy made full use of the liquid refreshments on offer, she was reportedly spotted with bottles of champagne, vodka and copious cocktails on her table. Sounds like our kinda party!

Unsurprisingly, the night finished in traditional big night out style – with Katy falling over. Don’t worry, Katy love, we’ve all been there.
“Katy was in high spirits and very excited that Justin was there, as she loves Justin. And she's good friends with Jessie, so they had a catch-up. Before long Katy had sunk a fair few vodka cocktails. She had big bottles of Ciroc and Belvedere on her table,” a snitch tells The 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.”
We feel for Katy, her hangover the next day could not have been fun.
