New Report: Neither Jackson Nor Rowe Are Biological Parents Of Michael's Three Kids

A new report claims that not only is Michael Jackson not the biological father of Prince Michael, Paris and Prince Michael II, but neither is the woman who delivered the two eldest, Debbie Rowe.

TMZ says "multiple sources" tell them that a sperm donor was used to fertilize donor eggs and that Debbie was just the surrogate.

Us claims that the sperm donor was none other than Michael's dermatologist (and Debbie's boss), Dr. Arnold Klein. But if Debbie truly was just a surrogate and not the biological mother, it's unclear if the identity of the biological mother is known.

As for "Blanket", the surrogate apparently didn't know whom she was hired by and her identity still remains a mystery.

Apparently there are documents in existence that detail the arrangements of the three births.

Even if it turns out that Debbie Rowe isn't their biological mother, she would still most likely have a claim in court for custody of Prince Michael and Paris because she was still their "birth mother."

It still remains to be seen if she'll challenge Katherine Jackson for custody.
