Celebrity website TMZ.com claims the Jacksons will transport the body to Neverland, in southern California, on Thursday.

They will then hold a wake on Friday or Saturday ahead of a funeral service on Sunday.

The part owners of Neverland have sent a letter to residents of Santa Barbara warning them of the madness that will occur when Jackson's fans flock to see his body.

Meanwhile, the singer's tour promoter has said hisill-fated show at the O2 Arena in London could be turned into a tribute gig featuring his family.

The president of AEG Live Randy Phillips told Sky's Kay Burley he saw Jackson rehearsing the day before he died and that he seemed fit and "engaged".

In an exclusive interview Mr Phillips denied Jackson was suffering from stage fright, saying AEGwould at "some point" release video of the rehearsals.

He said the show was going to be "beyond anything", adding: "At some point the world needs to see this production.

"I would imagine it could be done as a tribute with the family, with the brothers performing, some sisters, and the stars that were influenced by him.

"It would have been, which is the tragedy here, one of the most amazing shows ever, so at some point we want the world to see that."

Describing rehearsals, Mr Phillips said: "(Michael) was so amazing in the final week.

"He gave me a hug and said 'now I know I can do this'. He was that engaged and that incredible."

Earlier it emerged the singer's estate was valued at $236m (£142m) in March 2007 - but his father Joe, with whom he had a troubled relationship, will get nothing.

In his will, Jackson reportedly divides everything between his mother, three children and one or more charities - but there is no mention of Joe Jackson.

That is according to the Wall Street Journal which says the will could be submitted to the superior court in Los Angeles on Thursday.

Lawyer John Branca and music executive John Mclain, a friend of Jackson, are named as executors.

Mr Branca, who worked for Jackson from 1980 to 2006 and was rehired by Jackson a week before his death, wrote the will in 2002, says the Journal.

In an email message, a lawyer for Jackson's parents, L Londell McMillan, said neither he nor his clients had seen the 2002 will.

The size and complexity of the star's assets and debts is expected to pose a major challenge for his executors.

His assets, which include a 50% stake in Sony/ATV Music Publishing, could exceed his estimated debts of $500m (£300m) by as much as $200m (£120m), the paper said.

It is not known what custody provisions the 2002 will sets out for Jackson's three children.

His mother, Katherine, has been granted temporary custody of the youngsters - two boys and a girl - until a court hearing in August.
