Arnold Klein: Not Michael Jackson Sperm Donor "To Best of My Knowledge"

Arnold Klein skirted a question about being the dad of Michael Jackson's two oldest children on Good Morning America today.

"Not to the best of my knowledge," he said when asked by Diane Sawyer if he's the father of Prince, 12, and Paris, 11. "But I'm telling you, if push comes to shove, I can't say anything about it...but, to the best of my knowledge, I am not the father of these children."

"That's an intriguing phrase, 'to the best of my knowledge,'" Sawyer replied.

"Yes," he admitted.


"I can't answer it any other way," Klein went on. On June 30, he released a statement through his lawyer stating he was "aware of media reports" about the paternity but "because of patient confidentiality, Dr. Klein will make no statement on any reports or allegations."

Us Weekly has confirmed from multiple sources that Klein is Prince and Paris' biological father. Debbie Rowe, who worked for Klein for 23 years, is the biological mother. In the new issue of Us Weekly, Klein's longtime partner Stephen Price says that the kids called Klein "Uncle Arnold," and came along with Price as a guest to the Jackson house last Christmas.

The new issue also includes a 2003 interview with Debbie Rowe where she told Us Weekly's Ian Drew about her decision to carry Jackson's babies, "[Michael] said no at first. I had to nag him into it if you will. I really wanted to do it for him."

In the GMA interview, Klein spoke warmly of the children (Jackson also raised Blanket, 7), calling them "brilliant" and reminiscing about their last Christmas with their father. (The new issue of Us Weekly has exclusive photos from the gathering, which also included Star Wars icon Carrie Fisher.)

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

Klein last saw Jackson June 22 – three days before he died of cardiac arrest.

"He was not in terrible pain when I saw him. He danced in the office, and he danced for my patients," Klein said. "He was very muscular, and he was very, very happy and dancing.

"I saw nothing at that point that would make me worry whatsoever," he continued. "But I was always concerned about him because I was always worried about other doctors."

Klein also denied that he is under investigation for supplying Jackson with any prescription narcotics.

"I say that anyone who makes someone an addict or gives a person potentially dangerous substances directly to them to use, like [anesthesia] propofol is a criminal," Klein told Good Morning America. "It becomes nothing more than a manslaughter, or something worse than that.

"There was nothing wrong with the manner I treated Michael, because what I had to do is restructure for an individual who had lupus, who had terrible acne scarring his face," Klein added. "But I was not one of the doctors who participated in giving him overdoses of drugs or too much of anything. In fact, I was the one who limited everything, who stopped everything."

Regardless, Klein said, "no matter what he wanted, someone would give it to him. The very rich and the very poor and the very famous all get the worst medical care."
