According to a report in Us magazine, Jackson’s dermatologist and Rowe’s former boss Arnold Klein is the biological father to Prince and Paris.

"He is the dad," a Jackson insider told Us. "He and Debbie signed an agreement saying they would never reveal the truth."

In the case of Jackson’s youngest son Blanket, TMZ reports that the surrogate was never told that the baby was for Jackson.

A custody battle for the Jackson children has already begun, with his mother Katherine Jackson winning temporary guardianship. A hearing is set for August 3.

Rowe's lawyer Marta Almli disputed reports that her client was not the mother of the children, claiming the reports were "entirely false."
