Katy Perry keeps it real and tells Rolling Stone Magazine how hard it is to diet and keep her super hot body in check as she prepares for her California Dreams tour.

“After this interview I’m going to have a nice healthy breakfast,” she told the magazine. “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 10:00 p.m. and then go home and sort through e-mails concerning the production. I feel like I’m training for the Olympics!”

I love to her celebrities tell the truth about how it really is the SUCK to diet and lose weight/or stay super perfect. I want to slap those idiots that lie and say they eat whatever the want and just must have a good metabolism. Meanwhile they are living on Adderall, cigarettes and Starbucks.
