In an interview with Britain’s Mail on Sunday, La Toya says: “Michael didn’t want to know who the biological parents were. They took eggs from a donor and I believe the sperm came from one of five donors picked from a book. Michael didn’t know who the mother and father were. I don’t know who carried the child and if the surrogate knew whose child she was carrying.”

The paternity of Michael Jackson’s three children; Prince Michael I, 12, Paris Katherine, 11, and Blanket, 7; has been the subject of tabloid fodder in the weeks since the legendary singer’s death.

“Paris wants to be an entertainer. Prince Michael, the oldest, is assertive. I see such sadness there. He cried at the hospital but hasn’t cried since. He has become the little man of the family. Blanket is the baby. He is very funny, a real prankster like his father,” La Toya says.

“Those children were his greatest joy. He was a superstar but the only people who loved him unconditionally were the children.”

La Toya says she was shocked by the emergence of a 2002 will that named longtime Jackson family pal singer Diana Ross as a backup to family matriarch mother Katherine as the children’s guardian.

“Michael always told us that he wanted his eldest sister Rebbie Jackson to look after the children. Rebbie had a nice family, which Michael loved. He told many family members that she was his choice. We believe there is another will which will emerge. He updated his wills almost every five years, so we expect one to come out from 2007.”

La Toya also sounded off on reports that Michael’s former wife, Debbie Rowe, who gave birth to the two eldest children, will fight Katherine for full custody of Prince I and Paris. “These are not Debbie’s kids. They don’t even know she’s their mother. Like everyone else in his life, she was motivated by money. She has always said she’s not their mother.”

She stated, “Debbie has only seen the children a handful of times. Michael never introduced her as their mother.”

And Debbie Rowe isn’t the only person in Michael’s life on the receiving end of his sister’s displeasure. Dr. Conrad Murray, who was with the King of Pop at the time of his death, also has some explaining to do.

Michael Jackson died not in his own bedroom as first reported, but on the bed in the room of his doctor, Dr Conrad Murray, across the hall.

“I don’t know exactly what happened, whether he was giving him oxygen, but Michael ended up in the bed. The doctor was trying to give him CPR (resuscitation for cardiac arrest) on the bed.”

La Toya tried questioning Murray when she arrived at the UCLA Hospital where the King of Pop had been taken. She got nowhere.

She said: “Paris was in tears and said to me, “There’s Dr Murray. He’s the best cardiologist in the world, how can this happen to Daddy?”

“I said to him, “Tell me what happened?” But he was vague and simply said, “He just didn’t make it.” I wasn’t pleased with that answer, but you have to be careful as the kids were there. I felt weird and not right.”

“This was the only man who knew what went on, but he wasn’t telling me. And then he disappeared,” she added.

“Michael was murdered. And we don”t think just one person was involved. Rather, it was a conspiracy of people. I feel it was all about money. Michael was worth well over a billion in music publishing assets and somebody killed him for that. He was worth more dead than alive.”
