Arnold Klein, Michael Jackson's longtime friend, dermatologist and rumored biological father to Jackson's kids, spoke out in an interview with Diane Sawyer.

When Sawyer asked him about the speculation that he fathered Jackson's kids Prince Michael, Paris and blanket, Klein looked uncomfortable and responded, ""To the best of my knowledge I am not the father of these children," Klein said. "I can't answer it in any other way. I don't want to feed any of this insanity that is going around."

Debbie Rowe worked for Klein.

Klein spoke briefly about a Christmas Eve he spent with the singer and his "brilliant" children.

"The kids were so very happy and so beautiful," he said. "Every time they would pass their father they would say 'I love you Daddy.'"

Klein also saw Jackson three days before his death, and said he was fine. "He danced in my office," he said. "He danced for my patients... I saw nothing at that time that would make me worry."

As for investigations into doctors over-prescribing Jackson powerful drugs, Klein denied it was him.

"I was not one of the doctors who participated in giving him overdoses of drugs or too much of anything," Klein said. "In fact, I was the one who limited everything, who stopped everything."

He called the prescriptions Jackson had "poisons" and said he had Jackson flush some of them down the toilet.

He also denied prescribing Jackson the anesthesia drug Diprivan, which was found in Jackson's home.

"How am I going to prescribe Diprivan when I don't know how to use it?" he said.

But sadly, "no matter what he wanted, someone would give it to him."
