The trio of pop stars lead a charge of females that also included Rita Ora, Kelly Clarkson, Carly Rae Jepsen and Cover Drive's Amanda at the event at Wembley Stadium in London.

Katy delighted fans in a polka dot top and matching trousers bottoms as she closed the music extravaganza, which saw performances from the likes of Justin Bieber, Coldplay and Usher.

Cheryl Cole performing at the Summertime Ball:



"Well the thing is, I was really lucky enough to have it made by a woman called Pam Hogg – who specialises in making catsuits, " she said.

"But when you're doing such a big event like that [Summertime Ball], it's a stadium – we {Girls Aloud) played here before with Coldplay – people at the back can't see a thing.

"You know they might get the odd clip on the screen or whatever but you become teenie tiny, so I thought I'd be bold and bright and give everybody a view."

Rita Ora delighted the Wembley crowd in a casual shirt, which was fastened at her waist, while Amanda from Cover Drive's figure hugging outfit was the talk of the stadium.
