To Rolling Stone she also revealed her diet regime, saying she gets one day cheat where she would snack on burgers.
Katy Perry is treating fans to a taste of what only husband Russell Brand normally gets to see in a revealing new photo spread for Rolling Stone magazine. The provocative pop star appears on the cover of the latest issue of the publication wearing just a blush two-piece lingerie set and a sultry look, while she dons only fishnet stockings for one sexy beach shot inside the magazine.
Perry tells Rolling Stone she had to work hard to get in shape for the saucy spread - and her upcoming world tour. She explains, "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."
"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!"
"The Firework" singer also reveals she's incorporating smell-o-vision into her 90-plus shows: "It's the first concert that's going to smell good. It's going to smell like you're in cotton candy heaven. It's a fun little nuance."
Perry is also planning 15 costume changes on each night of the grueling tour, which begins in Portugal next month.
