The funnyman, who was joined by rockers including Steven Tyler and Billy Idol in his 1988 novelty cover of The Troggs’ Wild Thing, died in a car crash in 1992.
Now his pal, comic Carl La Bove, is claiming Kinison slept with his wife more than 20 years ago and fathered a child with her.
La Bove has been paying maintenance for nearly 13 years after splitting from the girl’s mother, but he has now filed legal papers claiming the child is Kinison’s.
DNA tests taken from the funnyman’s brother Bill allegedly show a 99.8 per cent likelihood the late TV star is the father of the unnamed offspring, who is now 21.
The test results also rule out any possibility La Bove is the father.
Bill Kinison says, “She looks like she’d be Sam’s daughter. Sam and Carl lived a lifestyle that was pretty promiscuous… I’d want to get that off me too.”
