David Gest has disputed the authenticity of Michael Jackson’s will.

The I’m A Celebrity star, who was best friends with The King Of Pop for over 40 years, told The Sun that he has concerns over the way his estimated $1 billion fortune is being handled by his lawyers:

“There’s a lot of questions about the will. One of the things people are wondering is how Michael was supposed to have signed that will in LA — when supposedly he was in New York that day.

“If he was in New York, how could he have signed it in LA?”

Jackson’s family has become embroiled in a bitter row over his estate during the last three years, resulting in several public confrontations, including a recent incident where his children were denied access to their grandmother Katherine by some of his siblings, something which Gest admits was unreasonable:

“Was it the wisest decision? No. The kids obviously panicked — justifiably so. They should have been able to speak to her. The family need to heal and come together as a unit.”
