That's the claim being made by a former bodyguard to Michael Jackson at least. He says that he was offered $500,000 to make a donation, a fee which he turned down, but he did make the donation. And at about the right time for the conception to have been possible.
MICHAEL Jackson's former British bodyguard Matt Fiddes will this week claim he is the biological father of the dead star's youngest son Blanket.
Fiddes, of Barnstaple, Devon, will tell Australian TV he fathered the eight-year-old by sperm donation for nothing - turning down a £500,000 offer from the superstar. He has told pals he will fight for custody if anything happens to Jacko's mum Katherine.
He's obviously going to have a fight on his hands over that claiming custody though. For a start, Diana Ross is named in Jackson's will as being the next in line to take custody. But more than that, assuming that they completed the paperwork for a standard donation, he will have given up all his parental rights anyway.
Hey, the story might even be true as well but I doubt very much that anyone's going to let such a rich child potter off with a claimed but unproven sperm donor.
