A Los Angeles dermatologist who treated Michael Jackson for years is the biological father of Jackson’s son and daughter, according to a bombshell new report.

Us Weekly magazine is reporting that Dr. Arnold Klein is the man who fathered Prince and Paris. The kid’s mother, Debbie Rowe, once worked for Klein as a nurse and Jackson met Rowe at Kleins’ Beverly Hills office when he was a patient. “He is the dad,” a Jackson insider said of Klein. “He and Debbie signed an agreement saying they would never reveal the truth.”

Both children look like neither of them

In 1993, Jackson told Oprah Winfrey he had a skin disease and instructed Klein to release an official statement disclosing the King of Pop’s pigmentation disorder. In the months prior to Jackson’s death, he made frequent visits to Klein’s Beverly Hills offices.

In addition, TMZ is reporting today that Rowe is not the biological mother of the two kids she claims she bore for Jackson. According to TMZ, all three of Jack’s kids were conceived in vitro – outside the womb with the help of an egg and sperm donor – and that Rowe was just a surrogate.

Neither Jackson nor Rowe ever admitted to the kids’ true lineage, although she confessed in 2002 that she carried the children as a personal favor. Following Jackson’s death on Thursday, Rowe told London’s News of the World that The Gloved One was not the children’s biological father, a report her attorney quickly said was false. Who knows?

“Prince” Michael Joseph Jackson, Jr. is now 11-years-old and Paris Michael Katherine Jackson is now 10-years-old. The mother of Jackson’s third child, Prince Michael II, remains a mystery.

Looking at the photo of Klein, you can’t help but notice the resemblance between him and the children.
