Perry: 'I'm obsessed with Leona Lewis'

Katy Perry has admitted that she is "obsessed" with popstar Leona Lewis.

The 'I Kissed A Girl' singer told BBC Radio 1 that she met Lewis backstage at the recent MTV Video Music Awards.

She said: "I met Leona Lewis, who I'm obsessed with, and I passed by the Jonas Brothers - they kept me 10ft away, though!"

The 24-year-old also confessed that she is a huge fan of UK comic Russell Brand.

"I met Russell Brand, who I'm in love with," she said. "I love him, he's so great - he's got the worst sense of humour in the best sense... I got every single joke."

Perry's debut album One Of The Boys will be released in the UK on September 22.
