Katy Perry made her sister tell their parents she was releasing 'I Kissed a Girl'.
The 'Firework' hitmaker couldn't bring herself to tell her pastor mother and father, Keith and Mary Hudson, about her risque single title in 2008 so avoided a confrontation by asking her sibling Angela to pass on the news.
Angela said: ''When Katy decided that 'I Kissed a Girl' was going to be her first single, I said, 'Have you told mom and dad?' And she said, 'No, but can you?' ''
Katy's father admits he was ''concerned'' when he heard the news because he feared it would affect his work, but insists the pop star's image has never impacted on him.
In a clip for Katy's forthcoming concert movie 'Part Of Me: 3D', Keith said: ''I was a little concerned, yeah, 'cause I thought my ministry after 30-something years is over. But, you know what? Never had a problem.''
Katy, 27, also insists the track never had any affect on her relationship with their family.
She said: ''I think people love the idea of 'a good girl gone bad'. And they think my parents have disowned me, but that's not the story at all.''
