Katy Perry has revealed that she keeps her hubby Russell Brand happy with a series of sexy “magic tricks” in the bedroom.

Perry said: "I have secrets and magic tricks, of course. I can't share them because then you'd all know. But let's just say I'm not shy. And I never wear sweats. Ever."

The star also revealed that the pair are house-hunting in Brand’s native London. She said: "We have a place together in America but we want to find somewhere here. I want a British passport."
