Michael Jackson's daughter Paris blames his 'This Is It' tour for killing him.
The 11 year old told her aunt La Toya Jackson her dad was pressured into working "non-stop" for his 50-date London residency - which was due to kick off at The O2 arena in July - and is certain it caused his death in June.
La Toya, 53, told UK TV programme 'The Paul O'Grady Show': "Paris asked me in the hospital, 'How could this happen? The cardiologist was the best, so how could this happen?'
"She said, 'You know, Auntie La Toya, they worked him too hard. He never got the chance to rest, it was just non-stop work.' I said, 'You're kidding,' and she said, 'You don't understand. They just worked him constantly and daddy didn't want that.' "
The 'Thriller' singer had been rehearsing for his London shows - which were expected to be his final tour dates - when he died.
However, before his passing Michael - who also had sons Prince Michael I, 12, and seven-year-old Prince Michael II, known as 'Blanket' - told La Toya he feared he would be killed over his huge song catalogue, which included tracks by The Beatles and other big name performers.
She revealed: "I thought that from day one. You must understand something Michael always told me. He said, 'If anything happens to me, if I die, it's because someone murdered me. They're trying to kill me'. It wasn't that he was being delusional, they did this over the catalogue.
"He owned The Beatles catalogue. Most entertainers out there, he owned their music. He would say, 'They're going to kill me over that catalogue. It's dangerous.' Look what happened."
Michael - who was allegedly addicted to prescription medications - passed away aged 50 from acute Propofol intoxication.
Propofol is a powerful anaesthetic used to put surgery patients to sleep in hospital.
La Toya said family members were taking a backseat while Los Angeles police carried out their homicide investigation into the singer's death, which has reportedly been focusing on his personal physician, Dr. Conrad Murray.
She said: "It's being investigated. We're working with police but leaving it to them to make the right decisions and we hope justice will be served."
