LATEST: Michael Jackson's ex-wife has hit out at allegations she told an Irish newspaper the pop superstar was not the natural father of their children, PRINCE MICHAEL JR and PARIS.

Debbie Rowe, who was married to Jackson for three years between 1996 and 1999, was reported to have claimed her eight-year-old son and seven-year-old daughter were both conceived using anonymous semen bought from a sperm bank.

She allegedly told the Sunday World, "Michael knows the truth - that he is not the natural father of Prince Michael Jr and Paris. He has to come clean.

"I have no information whatsoever about the identity of the semen donor for either child as such (semen) was obtained anonymously from a semen bank under an agreement of confidentiality."

But Rowe has rubbished the story, insisting she was in the US nursing a cold at the time of the alleged interview.

Her lawyer IRIS FINSILVER said Rowe would never make a press deal which might risk her visitation rights.

He tells the New York Daily News, "Rowe never spoke to any newspaper."
