Perfecting her cutesy pose, Katy Perry was among the celebrity attendees at the Capital FM Summertime Ball in London this afternoon (June 7).

In front of 55 000 people at the Emirates Stadium, the I Kissed a Girl singer performed a string of her hits all in the name of charity. Capital’s owner, Global Radio, has promised to donate $160 000 from the proceeds to Help a London Child.

Over 16 world class pop acts joined Katy at the star-studded event, including Lionel Richie, Leona Lewis, Kelly Clarkson, Enrique Iglesias, Ciara and Akon.

Meanwile, Katy says she would love to emulate Britney Spears’ spectacular ‘Circus’ tour.

The campy pop star has to make do with a smaller budget, but one day hopes to rival Britney and aby putting on a massive stage show.

She says: “I really want to see (Britney’s) show. I hear it’s supposed to be amazing and I love those big production shows, because I haven’t been able to get to that point yet. I’m on my first record. I don’t have millions of dollars to do shows like that just yet. I love how she uses all the dancers and all the theatrics.”
