Kelly Clarkson leaving Radio One, London, England - 11.01.09

The Since U Been Gone singer can't put the vampire love stories down.

She says, "I'm on Breaking Dawn. It's actually interrupting my sleeping pattern... I'm crazy.

"Every girl is, like, obsessed. I went to Cancun, Mexico for New Years with a bunch of friends and we were laughing because, as we were laying out (sunbathing), literally every female at the pool had one of the books from the Twilight series."
