MICHAEL JACKSON's youngest son still does not fully understand that his daddy has died, it has been revealed.

Prince Michael II - known  as ‘Blanket' - is struggling to believe that his father is never coming home and asked family if his daddy is simply ‘on holiday.

Michael's longtime pal MARK LESTER said the The King of Pop's seven-year-old son  is utterly bewildered.

Mark, godfather to Jackson's three children, revealed he had the emotional conversation with the confused seven-year-old after the moving memorial service to the King of Pop in Los Angeles.

The 50-year-old former child actor said: "It is obvious to me that Blanket is still unsure about what exactly happened to his father.

"He said, ‘Where's Daddy gone? On holiday?' It was a rhetorical question and it broke my heart.

"Prince was taciturn, unusual for him, but we still had a hug.

"Paris gave me a tight hug and we just held each other for a while. We were both welling up. I told her that her dad would always lie in her heart and be remembered by at least half of the world

Paris replied: ‘I'm just glad he is at peace'."

Mark spoke as it emerged police are unlikely to bring murder charges against any of the doctors who treated the 50-year-old pop star in his final days.

The singer had made plans with Mark to spend this Christmas together and Paris, 11, told him she already had presents for his children.

Mark added: "She was disappointed my daughters weren't able to come to the memorial. She asked me, ‘Can we come and stay with you at Christmas and I can bring the presents?'

"I was very touched and hope that can still be arranged.

"It's difficult to say until the custody arrangements have been finalised." Mark is also planning to attend a second funeral, when Michael's body is finally laid to rest.

He said: "Paris asked if I would bring my children, too.

"I know it would be a comfort to her as well as Prince and Blanket but I'm waiting on confirmation of a time and place."

Mark said a possible custody row over the singer's three children would be "disastrous" if they were split up.

He insisted Paris and Prince, 12, have no relationship with their biological mother Debbie Rowe.

And he said he could not bear the idea of the pair being separated from Blanket, whose real mum is not known.

He said: "The children don't know her [Debbie Rowe] and haven't seen her for years.

"They are exceptionally well taken care of in a loving environment.

"The possibility that the three children might be split up - Blanket, of course, is by another mother - is unthinkable and I believe it would be disastrous for all of them."
