Katy Perry branded `Devil Child` by dad

London: Katy Perry`s own father has branded the pop star as a "devil child."

Firebrand preacher Keith Perry has claimed that watching his daughter`s concerts is so hellish that he ends up weeping because the fans are worshipping the singer instead of God, the Sun reported.

Keith also urged congregations to "pray for Katy."

Keith and his wife Mary , who are currently touring American churches as star speakers and have made millions off the back of their famous daughter, showed a video making Katy out to be a "devil child" who needs "healing".

Speaking in Santa Fe Springs, California, Keith said that people ask him how can he preach if he has produced a girl who sang about kissing another girl?

"I was at a concert of Katy`s where there were 20,000. I`m watching this generation and they were going at it. It almost looked like church," he said.

Keith added that he stood there and wept and kept on weeping and weeping because according to him the audience were loving and worshipping the wrong thing.
