MICHAEL Jackson's funeral could be the world's biggest with plans to put his body on display at Neverland and throw open the estate's gates to the masses.

As reports named the superstar's skin doctor as the true father of his two eldest children and new documents revealed the depth of his financial ruin, Jackson's family is considering allowing fans a grisly last look at the singer's body.

If local authorities approve the plan, a 30-car motorcade would accompany the superstar's body from LA to his sprawling fantasy estate about 250 kilometres away ahead of a public viewing Saturday and a private memorial Monday (AEST).

Jackson's lawyer yesterday discovered that Jackson had left a will, despite his parents' belief the pop star had not.
