Katy Perry is preparing for her California Dreams world tour, and the 'California Gurl' told Rolling Stone just how she plans to get in shape.

"After this interview I'm going to have a nice healthy breakfast," the 5'8" star said. "I'm on a meal plan, which absolutely sucks, but on Sundays I get to have a cheat day where I go buck wild and eat In-N-Out Burger. Then I'll work out, go to a vocal lesson, run through the entire set at rehearsals, go to dance rehearsal until 10PM, and then go home and sort through e-mails concerning the production. I feel like I'm training for the Olympics!"

"Touring is no longer an ordinary thing where you play an instrument in jeans and a T-shirt," Russell Brand's new wife admits. "It has some pizzazz these days, and I'm definitely bringing the pizzazz with a lot of bells and whistles. This show has a Broadway feel to it. It's got a story line that's going to be very interesting, kind of loosely based on my life, but a cartoon version."
