Katy Perry discusses her diet

Katy Perry has dished (ha-ha) the details on her diet.

The singer is on a strict diet in preparation for her California Dreams world tour.

“After this interview I’m going to have a nice healthy breakfast. I’m on a meal plan, which absolutely sucks,” she explained.

“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!”

“I just really want to raise the bar. Touring is no longer an ordinary thing where you play an instrument in jeans and a T-shirt,” she said.

“It has some pizzaz these days, and I’m definitely bringing the pizzaz with a lot of bells and whistles. The show has a Broadway feel to it. It’s got a storyline that’s going to be very interesting, kind of loosely based on my life, but a cartoon version.”
