Joe Jackson is pissed at Michael Jackson's former best friend/doctor, Arnold Klein, for telling TMZ MJ was gay and had a relationship with Klein's office manager.
Joe railed at Klein, telling TMZ, "It's not true. Michael was not gay."
Joe feels Klein has betrayed his son: "He has no respect for Michael ... to say things about him when he's gone is shameful."
Jason Pfeiffer was on TV last week, claiming he had a sexual relationship with Michael, and Dr. Arnold Klein spoke of walking in on the two men and seeing them with their shirts off. In the last few days, Dr. Klein has told TMZ Jackson was gay and had no problem with people knowing about it.
Joe Jackson went on, "He's a doctor and knows better than to break his vows against a patient."
