Dr. Arnold Klein is Tweeting back at Elizabeth Taylor over the legendary actress' recent implication that he supplied Michael Jackson with lovers ... of both genders.
The Twitter-tongue-lashing he got resulted from comments he made about MJ's sex life, saying he was gay and confirming rumors of an affair with Jason Pfeiffer.
Taylor lambasted Klein for betraying Michael's confidentiality and trust, and got in an extra dig that the dermatologist supplied Jackson with men as well as women.
Both Pfeiffer and Jackson's former wife Debbie Rowe worked in Klein's office (Klein is also rumored to be the father of MJ's kids, but that's neither here nor there).
He counter-Twittered Friday: "Dearest Elizabeth Michael CHOSE whom he loved; I only SUPPLIED medical care. May God bless you and Michael. Your friend Arnie."
Was Michael Jackson gay? Is Arnold Klein lying? Did the doctor betray the star's trust? Was Elizabeth Taylor out of line? The list of questions goes on and on ...
