Los Angeles, Oct 28 (IANS): Television veteran David Gest, known to be best friends with late legendary singer Michael Jackson, has questioned the validity of his will.

Gest, 40, has shown his doubts on the validity of the will, on the distribution of MJ's assets estimated to be worth $1.6 billion.

David's accusation echoes claims by some of MJ's siblings, who say there is evidence he was with family friend Al Sharpton in New York on June 7, 2002, the day he siged it.

"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," thesun.co.uk quoted Gest as saying.

?If he was in New York, how could he have signed it in LA,? he asked.

The terms of the document leave sole control of his estate, growing by millions every day from posthumous record sales, to two lawyers - John Branca and John McLain.

MJ died June 19, 2009 and his relatives are still battling for a cut of his estate three years after his death.
