Rowe Not Kids' Bio-Mom: TMZ

Not only was Michael Jackson not the biological father of any of his children, neither was Debbie Rowe, his ex-wife, their biological mother, TMZ reports. All three children were conceived in vitro, and Debbie acted as the surrogate for the eldest two—for a fee—sources tell TMZ.

Even so, Rowe is the presumed biological parent since she was married to Jackson when the children were born, TMZ notes, so she could theoretically win custody. The identity of Jackson’s youngest child’s surrogate is still unknown, but sources say she was never told of Jackson’s identity. (More Michael Jackson stories.)
