Grace Rwaramba, the 42-year-old nanny who cared for Michael Jackson's three children, said she routinely had to pump out the singer's stomach after he'd ingested a dangerous combination of drugs.

"I had to pump his stomach many times. He always mixed so much of it," Rwaramba tells The Times of London, referring to drugs. "There was one period that it was so bad that I didn't let the children see him," she is quoted as saying. "He always ate too little and mixed too much."

Rwaramba was introduced to Jackson more than 15 years ago by mutual friend Deepak Chopra, who ironically says some of her quotes in The Times were taken out of context.

"For the record, Grace never pumped Michael's stomach. She has no idea how she would even do such a thing," Chopra - spiritual teacher, medical doctor and Jackson's longtime friend - wrote on his Web site Sunday. He also says of Rwaramba, "Grace is more than my best friend - I refer to her as my sister."

Having now arrived in Los Angeles from London, Rwaramba, who is originally from Rwanda, is expected to be interviewed by LAPD detectives investigating Jackson's death on Thursday, according to People.

Rwaramba at one point proposed a famliy drug invention for Michael in Vegas, and went so far as to contact his mother Katherine and sister Janet for their help with it. But when Micahel found out about her efforts, he fired her - temporarily.

"He didn't want to listen," she says, "that was one of the times he let me go."

In Jackson's employ for more than a decade, Rwaramba started as an office assistant to the pop star before becoming a nanny to his three children: Prince, now 12; Paris, 11; and Blanket, 7. She was last fired by Michael in December, and claims that when she visited the children in April, she herself had to buy balloons for Paris's birthday, because Michael was so broke.

"Michael had no idea about money," Rwaramba says, citing a $1 million offer he received to appear in Japan. "By the time everyone took their share," she says, "he ended up with $200,000."

According to Rwaramba, on Friday, the day after Michael died, his mother Katherine called her from Michael's Holmby Hills house and asked where he kept his cash.

"She said, 'Grace, the children are crying. They are asking about you. They can't believe that their father died. Grace, you remember Michael used to hide cash at the house. I am here. Where can it be?' "

Rwaramba advised looking "at the garbage bags and under the carpets." Then, said the former nanny, "She said, 'Grace, where are you? Come. I will pick you up from the airport.' She sounded so strong. So strong!"
