When the Last Friday Night hitmaker wed the former sex addict, she knew she would be in for a wild ride.
And Katy is proud to admit her and Brand, 36, enjoy an active sex life.
She said: 'I don't think being married means you're in any way boring. I married Russell Brand, so it's definitely not boring! It's a laugh a minute. We keep ourselves busy. You know, I don't just have sex once in a while!'
But there is another side to the couple's home life, says Perry.
The 26-year-old, who married the British funnyman in India last October, added to British Look magazine: 'There's never a dull moment. He's a real handful, but handfuls can be fun! A sense of humour is really important in our household and that's how we de-stress. We're really good friends.
'My favourite time is when it's just us at home with our cats and we're having fun.'
