Katy Perry certainly made the most of her stay in London. After performing at Capital FM's Summertime Ball at the weekend the singer headed to London's Cirque Du Soir club where she partied until the wee small hours.
But after four hours of drinking with the likes of Jessie J and Justin Bieber, the singer had a little bit of trouble negotiating her way out of the club and had to have a helping hand or five to get her to her car after apparently falling to the floor inside.
Despite being spotted with her boyfriend, Robert Ackroyd on more than one occasion during her visit to the capital, Katy was keen not to be snapped with the Florence + The Machine guitarist as they left at 5am.

The pair have rekindled their romance after putting it on hold in May after hooking up at the Coachella music festival.
And we think Katy might have still had a bit of a sore head as she arrived back in LA earlier today. She was spotted covering her head in a blanket as she walked through LAX. A Chanel blanket obviously.
Meanwhile, Katy is being lined up to for a role in a new movie about Freddie Mercury. She's being tipped to play the late Queen singer's girlfriend Mary Austin opposite Sacha Baron Cohen as Freddie.
