Katy Perry's post-tour party
Katy Perry has revealed she is planning to go "wild" when her tour ends after having to stick to a healthy diet and avoid alcohol.
The 26-year-old Firework singer - who is married to teetotal and former drink, drug and sex addict Russell Brand - was quoted as telling The Daily Star she has to behave on tour to keep her voice in good shape, but admits she is fed-up of not indulging herself.
Katy revealed: "I'm pretty boring on the road because I save it all for the stage, so I'm on a strict vitamin diet.
"But when the tour is over I'm going to be a devil and hit a wild streak."
She joked: "I'll be face down in the porcelain."
Katy revealed: "I can't eat spicy food or dairy because they're bad for your voice. I can't even do coffee.
"So you'll find me staring at the white wine in the fridge backstage."
The I Kissed A Girl singer said she misses her cats, Kitty Purry, Morrissey and Kristy when she's on tour.
She said: "I miss my kitties. One time I asked Russell to bring the cats with him so we could all hang out.
"Putting a cat on a plane is strange, but I always make sure it's in first class."
