Katy Perry has revealed that she will be letting her hair down after her California Dreams' tour.
The singer is on a strict diet and booze ban whilst on tour but has said she plans to hit 'a wild streak' when the tour ends.
''I'm pretty boring on the road because I save it all for the stage, so I'm on a strict vitamin diet,'' Perry told the Daily Star.
She added: "But when the tour is over I'm going to be a devil and hit a wild streak. I'll be face down in the porcelain.
"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."
Perry's California Dreams world tour has already called in the UK, but the singer is set to return for another leg in the autumn.
The tour is in support of Perry's recent album 'Teenage Dream'.
