Michael Jackson's ex-wife Debbie Rowe just broke down in tears while testifying in the MJ wrongful death trial, claiming the singer's doctors held a "pissing match" to outdo each other by giving Jackson the "better" drugs ... a competition that fueled his deadly drug addiction.
On the stand, Rowe pointed the finger at two doctors specifically -- Dr. Arnie Klein and Dr. Steven Hoefflin -- claiming MJ trusted them to prescribe his pain medication, and they consistently tried to one-up the other by giving MJ increasingly stronger doses of painkillers.
Rowe said Dr. Conrad Murray then "got in there and killed him." She added, "I was probably one of the only ones who said no to MJ."
Rowe said MJ had a notoriously low tolerance for pain, which paved the way for the abuse of painkillers like Demerol and Diprivan.
Rowe called Klein and Hoefflin idiots for going back and forth at the same time, trying to outdo each other and not looking out for MJ's best interest.
