Arnie Klein To Larry King: ‘I Once Donated Sperm,’ Warned Jackson About Drug

Arnie Klein, Michael Jackson’s dermatologist, denied being the father of Jackson’s children – at least, to the best of his knowledge.

During an interview Wednesday on CNN’s “Larry King Live,” Klein said he did donate sperm, but to a bank and not to the singer.

“I still can’t answer [the paternity question] absolutely one way or another,” Klein said. “I once donated sperm.”

He said his donation was “absolutely not” for Jackson, responding to reports that he could have fathered Jackson’s son Prince Michael, 12, and daughter Paris Katherine, 11, with Jackson’s ex-wife Debbie Rowe, who once worked for Klein.

“I think what’s most important about this whole thing … is who the children want their father to be,” Klein said, leaving open speculation that he could be the children’s biological father. “To the best of my knowledge, I’m not the father,” he added.

Klein also said he on occasion gave the pop star the painkiller Demerol but warned him about using the powerful sedative Diprivan.

Dr. Arnold Klein tells CNN’s “Larry King Live” that Demerol was among the strongest drug he prescribed Jackson and doesn’t know how he got Diprivan, usually administered by anesthesiologists in hospitals.

Investigators looking into the cause of Jackson’s June 25 death have homed in on drugs given the insomniac musician. Diprivan was allegedly found in Jackson’s home.

The dermatologist says: “If you took all the pills I had given him in the last year at once, it wouldn’t do anything to you.”

Klein said Wednesday he discovered that Jackson was using Diprivan while on tour in Germany. Klein told Jackson the drug was dangerous: “I told him he was absolutely insane.”
