Prince Jackson - has reportedly requested a DNA test is performed on Dr. Arnold Stein to determine, once and for all, if he's his biological father.
Stein died last week age 70, taking to the grave the truth over whether or not he was indeed the real father of the teenager.
There has long been speculation that the three children the late King of Pop fathered with ex-wife Debbie Rowe - Prince, 18, Paris, 17 and Blanket 13 - are not genetically his.
According to insiders, Prince Michael knows that Stein's death may be the last chance for him to find out the truth about who his father is.
“Prince is demanding that he find out once and for all who his real flesh and blood is," a source reportedly told RadarOnline.
"He is demanding to have a DNA test done on Arnie’s body before he is buried to determine who his biological father is once and for all,” said the source.
Last week Prince appeared to respond to the claims that the Thriller star was not his father.
Answering a tweet which said: "Everyone knows you are a Rowe-Klein NOT a Jackson!! Yall should stop trying to put on a FAKE front and get real."
