Debbie Rowe injected Michael Jackson with drugs when she worked for the singer’s dermatologist.

According to TMZ, Debbie Rowe frequently injected Michael Jackson with drugs while she worked for Jackson’s dermatologist, Dr. Arnold Klein.

TMZ obtained law enforcement documents from Jackson’s 2005 molestation trial that included an affidavit from a Santa Barbara County Sheriff’s deputy who served a search warrant on Dr. Klein in 1993 to obtain the singer’s medical records.

The deputy wrote in the affidavit “Ms Rowe observed the back of Jackson’s body while she gave him massages to help him sleep.  Ms. Rowe also observed Jackson’s buttocks on numerous occasions when she gave him injections prior to acne treatments.

The affidavit did not specify the type of drug administered.
