A man has come forward claiming to be the biological son of Prince just weeks after the artist's death.
Carlin Q. Williams alleges that the late legend is actually his real father. The Missouri man filed a petition on Monday to be declared the icon's 'sole surviving legal heir', and has even requested a blood test.
Prince, whose full name was Prince Rogers Nelson, was found dead at age 57 at his Paisley Park home-studio complex in a Minneapolis suburb on April 21.
Mr Williams, meanwhile, who is believed be in jail on weapons charges, has stated his claim to paternity publicly, writing on his website: 'I Am Prince The Singer's Son'.
Lawyers charged with untangling the multimillion-dollar estate of late pop star were able to get a sample of his blood from the coroner so they can analyze the singer's DNA for exactly this eventuality, in order to verify any paternity claim.
He is not known to have had any children, but in a court order dated on Friday, Minnesota District Court Judge Kevin Eide had foreseen that parentage issues might arise as the probate case goes forward.
He authorized the estate administrator, Bremer Trust, to analyze Prince's blood, including conducting genetic testing and any other analysis required for the administration of the estate.
The exact value of Prince's estate has not yet been disclosed but his music catalog alone has been estimated at more than $500 million.
Administrators of his estate said they still had not found a will.
In the absence of a will, six siblings or half-siblings of the star have been listed as his heirs in court documents filed in Carver County District Court in Chaska, Minnesota.
In an affidavit filed today, Williams' mother, Marsha Henson, claimed that she met Prince in July of 1976 at a hotel in Kansas City, Missouri. Shortly thereafter, she claimed in the affidavit, they had sexual intercourse and conceived a son.
Nine months later, she gave birth to Carlin Q. Williams on April 8, 1977, she added.
Williams is currently serving time in federal prison in Colorado for weapons transport, according to federal court records obtained by ABC.
