Katy Perry has always enjoyed rebelling against her parents and can't resist pushing their ''red button''.
Katy Perry says her parents were strict with her because they didn't want her to "turn out like a prostitute".
The pop star has always enjoyed rebelling against her Christian pastor parents Keith and Mary Hudson and regularly tested their rules when she was growing up.
She joked to Q magazine: "Some people are fascinated with the idea of a great storyline: good girl, Christian parents, goes bad. My song 'I Kissed A Girl' provided the perfect storyline, so it's entertaining for people. My parents were really strict at first, because they didn't want me to turn out like a prostitute.
"There's a button that all kids have with their parents. It's like this red button that we push. And the paint has chipped off of my red button in a few places because of the constant pushing."
Katy - who got engaged to reformed ladies' man Russell Brand in December after a whirlwind romance - is still upsetting her parents now by agreeing to be a part of 'The Smurfs' film.
The 25-year-old singer voices the character of Smurfette in the new animated movie - which is based on the 80s cartoon series about the miniature blue-skinned characters - and has revealed her mother and father disapproved of the show when she was a child.
She added: "My parents felt that the Smurfs' reliance on sorcery and magic was sending the wrong messages to me as a child. But it seems I am destined to push my mother's red button.
"They stopped me watching 'The Smurfs' and I f***ing became one. They banned me from eating sugar and I got sugar. I cannot be f***ing well stopped, baby!"
