Katy Perry hasn't "tamed" Russell Brand.
The 25-year-old brunette beauty laughed off claims she has curbed the British funnyman's womanizing ways, insisting she met him at a time in his life when he was ready to settle down.
She told Guardian Weekend magazine: "We all start to slow down. I think he was ready for change. I mean, you don't have the stamina to be in bed with 80 different women a week when you're 35 and trying to do good work.
"It's not about taming, because that won't last. Not everything stays perfect."
Katy also admitted she occasionally has to "remind" Russell - who doesn't drink alcohol or take drugs after overcoming addictions - of their differing lifestyles, but insists her desire to go out partying with friends never causes any serious problems.
She said: "He knows that I'm young and have friends and a social life and he was attracted to me. Not, 'Oh let's find a version of myself in a female.'
"Every once in a while I need to remind him of that and he listens. It's about communication."
The 'California Gurls' star also spoke of how well her parents, pastors Keith and Mary Hudson get on with her fiance.
She said: "My mother is in love with Russell. And my father, I think he sees a lot of himself in him."
