Christian mother calls Perry's hits 'disgusting'

Katy Perry‘s mum is set to release a potentially embarrassing tell-all book.

Mary Hudson, who runs a Christian ministry in California with her husband Keith, has supposedly written a memoir which details how her daughter’s raunchy image has affected her religious beliefs.

The New York Post reports that Hudson reveals what she really thinks of Katy‘s hit ‘I Kissed A Girl’ in the as-yet-untitled memoir.

“I hate the song,” she said. “It clearly promotes homosexuality and its message is shameful and disgusting.”

She added: “Katy knows how I feel. We are a very outspoken family and she knows how disappointed her father and I are. I can’t even listen to that song.

“The first time I heard it I was in total shock. When it comes on the radio I bow my head and pray.”

There’s no word on when we’ll be able to pick up a copy of the book yet.
