Michael Jackson's dermatologist, Arnold Klein is THE REAL FATHER of Jackson's kids!

US:
Though Michael Jackson was wed to Prince and Paris' mother, Debbie Rowe, their biological father is Arnold Klein, Jackson's L.A.-based dermatologist and Rowe's former boss, multiple sources confirm to the new issue of Us Weekly.

"He is the dad," says a Jackson insider. "He and Debbie signed an agreement saying they would never reveal the truth."
Though neither Rowe nor Jackson ever confessed to their kids' true lineage, she did admit in 2002 that she carried his children as a personal favor (and would not confirm that the marriage was ever consummated).
"I said, 'Let me do this. You need to be a dad. You have been so good to me,'" Rowe -- who met Jackson when she was a nurse's assistant in the 1980s -- has said.

Klein would not give a comment to Us.
