ENGLAND — Kerry Katona was once the front woman for all-girl pop band Atomic Kitten. Now she’s supposedly the star of a secret celebrity sex tape.Say it isn’t so!

Katona says it isn’t so.

According to the now twice-married 25-year-old mother of three, although the naked girl looking so happy bouncing diddling herself for the camera may well look like her, but it’s not her. And the man looking on proudly from the side is not her former taxi driver husband, Mark Croft.

Yes, it’s true she’s had a few wild moments in her life. There were her mother’s suicide attempts. There were her appearances on Britain’s Sexiest… and Loose Women. There was her battle with depression, drugs, and alcohol after her first divorce. There was her time in rehab. And there was that naked photo in the UK tabloid, The Sunday Sport.

But that’s all behind her now.

“It’s definitely not me,” she says of the website footage boasting to feature her. Whoever the girl is, she’s obviously enjoying herself, so good luck to her! If it provides frustrated people with a few moments of pleasure, then I’m very happy for them.”

Maybe she’s telling the truth. Maybe she never did let her hubby videotape her pleasuring herself.

After all, they called her the lead singer for Atomic Kitten, but, as she later admitted, she never sang a note on any of the band’s songs.
