According to a report on gossip site TMZ.com, Michael Jackson is not the biological father of his three children. Michael Jr., Paris, and Prince Michael II were apparently conceived in vitro, with neither Jackson nor Debbie Rowe, the putative mother to Michael Jr. and Paris, contributing biological material to the children. The biological father to Jackson’s two oldest children was reported by Us Weekly to be Jackson’s dermatologist (and Rowe’s former boss), Arnold Klein. TMZ reports the identity of Prince Michael II’s biological parents remain a mystery, perhaps even to Jackson himself, and his surrogate mother was kept in the dark about whom would eventually take custody of the child. Further complicating matters surrounding custody of the children, Jackson reportedly never filed adoption papers for any of his kids, believing no third party would ever lay claim to them.
