The parents of singer Katy Perry have condemned her chart-topping single “I Kissed a Girl”.

The song, which includes the lyrics “I kissed a girl and I liked it, the taste of her cherry chapstick”, was an instant number one hit on U.S. music charts.

Perry’s parents, Evangelical preachers Mary and Keith Hudson, spoke out against the song.

Mrs Hudson said: ‘We hate it. It promotes homosexuality, which the Bible clearly states is a sin, and it is shameful and disgusting.

“When it comes on I bow my head and pray.

“She is our daughter and we love her and can’t cut her out of our lives.

“But we strongly disagree with how she is conducting herself and she knows how disappointed we are.

“Katy is not a homosexual and has just been led astray by Hollywood.

“She changed when she went to LA and is going through a period of rebellion.

“She’s told me, ‘Oh Mum, I’m not going to turn into Amy Winehouse,’ but I pray all the time God will help her find salvation.”

Katy Perry’s first album, comprised of Christian songs, was released in 2001, and nowhere near as popular as her current album One of the Boys.
