Carlin Williams

A Missouri man filed a paternity claim naming himself the “legal heir” to Prince Rogers Nelson’s estimated $800 million fortune.

Carlin Williams, who is an inmate at Colorado’s “supermax” federal prison, filed a paternity claim from behind bars.

Williams, 39, claims his mother met the pop icon at a hotel in Kansas City, Mo. in July 1976 (when Prince was still in high school). Williams further claims his mother and Prince had consensual unprotected sex. The court documents state Williams was born in April 1977.

NY Daily News — Prince would have been 18 at the time, fresh out of high school and several years away from superstardom. His debut album, “For You,” did not come out until 1978.

Court papers do not state Williams’ claims for his stake in Prince’s estimated $300 million estate.

Williams is serving a seven-year sentence for firearm possession, after he was caught with a .32 caliber pistol that was transported in interstate commerce, records show. He will be imprisoned until 2020.

A Minneapolis judge last week ruled that DNA samples must be supplied to anyone making a paternity claim. The judge allowed four months at the time limit for paternity claims to be filed against Prince’s estate.
