Prince is NOT the father of the federal prisoner who claimed he was the singer's long-lost son ... according to Maury Povich DNA testing.
Sources with direct knowledge of the case tell us the DNA test returned a 0.0% chance that Carlin Q. Williams is Prince's spawn. In docs, Carlin said his mother met Prince in 1976 and knocked her up in a Kansas City hotel.
Carlin -- in prison for gun possession -- is one of several people who've come out of the woodwork claiming blood relations. Another woman, Taz Walker, also claims Prince was her pops.
