NEW YORK - The former nanny of Michael Jackson’s children has said the singer’s stomach had to be pumped on a regular basis to remove dangerous cocktails of drugs.

Grace Rwaramba, who worked for Jackson for more than a decade before being dismissed last December, claimed the King Of Pop often mixed too many drugs at the same time.

The Thriller hitmaker is thought to have been taking up to eight different drugs a day, including three narcotic painkillers, in the days leading up to his death.

“I had to pump his stomach many times. He always mixed so much of it,” the New York Daily News quoted Rwaramba as telling British newspaper The Times.

“There was one period that it was so bad that I didn’t let the children see him . . . He always ate too little and mixed too much,” she added.

The 42-year-old, from Rwanda, began working as an office assistant before becoming nanny to Jackson’s kids, Michael Jr, known as Prince, 12, Paris, 11, and Prince Michael II, 7.

Jackson’s increased drug dependency was said to have begun taking its toll on his mental and physical health days before he died on Thursday.

The 50-year-old was claimed to have suffered further exhaustion stemming from rehearsals for his 50 comeback concerts, which were due to begin in London at O2 arena on July 13.

Medical examiners in Los Angeles are yet to determine the cause of his sudden death, but coroners confirmed Jackson was on prescription medication. (ANI)
