Katy Perry could be a preacher

Katy Perry's mother believes she could be a preacher.

The 'Teenage Dream' singer's parents Mary and Keith Hudson - who are both Christian pastors - have conflicting feelings about her pop career but her mum can see her skill her gift for entertaining a crowd being used for a spiritual purpose.

Expressing her desire to see Katy become "a Kathryn Kuhlman type of healer" - an evangelist and faith healer who began preaching aged 16 - Mary wrote in a proposal for a new book about her daughter's impact on her ministry: "I recognised the psalmist gift in her performance. Yet she sang out, 'I kissed a girl, and I liked it,' while thousands joined her. One part of my heart soared . the other part broke for the thousands of hungry souls being fed something that didn't nourish their spirit, but fed their flesh."

According to the New York Post newspaper, the proposal also details how Mary feels uncomfortable with her daughter's flesh flashing stage outfits, but refuses to voice her disapproval.

Recalling an incident backstage at one of the 26-year-old star's concerts, Mary wrote: "Katy stepped out from behind the changing doors in a tiny risque costume. No mother wants to see the top of her daughter's boobs . My first instinct was to order her back behind those doors and demand she put something else on . However, I had no problem letting my eyebrows say what I wouldn't allow my mouth to utter."

While Mary insists she is happy with the successes her daughter - who is married to British comic Russell Brand - has achieved, she admits she worries about "saving" her from the music industry.

She added: "Oh, dear God, how can I save her from all this? The money, the fame, the network, the people surrounding her, how can I compete?"
