Jackson's ex-wife testifies about his fear of pain

Michael Jackson's ex-wife broke into tears as she described the singer's fear of pain and trust of physicians.

Debbie Rowe took the witness stand today in a negligence lawsuit filed by Jackson's mother against concert promoter AEG Live LLC.

Rowe says the pop star trusted doctors to prescribe pain medication to him, but they sometimes tried to outdo each other while losing sight of Jackson's care.

Rowe worked for Jackson's longtime dermatologist Dr. Arnold Klein. She says Klein and another physician, Dr. Steven Hoefflin, would try to out-do each other in the medications they gave the singer.

Rowe said she was with Jackson when he received treatments from both physicians.
 

Katherine Jackson claims in her lawsuit that AEG Live failed to properly investigate the doctor convicted of giving her son an overdose of anesthetic in 2009. AEG denies any wrongdoing.
