Three years after the death of pop legend Michael Jackson, his family has descended into all-out war. And at the centre of their bizarre feud, including allegations of kidnapping, are his three children and their generous trust fund. Global news outlets have been in a frenzy trying to piece together the mysterious disappearance of family matriarch – and legal guardian of Prince Michael, Paris and Blanket – Katherine Jackson, with 14-year old Paris tweeting frantically in a bid to track down her beloved grandmother.

Now, in a world exclusive, Woman’s Day can expose how the extraordinary events of the past week led Debbie Rowe – mother of Paris and Prince – to make a return to their lives. Her decision comes as Michael’s siblings call into question their frail mother’s ability to raise his children.

“On July 14, Michael’s oldest sister Rebbie and his brothers Randy and Jermaine arrived at their mother’s LA mansion with a doctor who claimed to be the partner of her usual doctor,” says our source, who has strong ties with two senior members of the Jackson family. “He asked her some questions and then told her his ‘diagnosis’ was exhaustion and that she needed to get away from the children immediately and rest.”

Our insider says Randy, Jermaine and Rebbie took the 82-year-old to an apartment in Arizona – without the knowledge of Paris or her brothers. “Paris was out horse riding and Prince and Blanket were at karate, so when they got back their grandmother was gone,” says the source. “There was a note from their Aunt Rebbie saying, ‘Don’t worry, we’ve taken Grandma on a surprise holiday.’”
