William Shatner is being sued for $170 million by a man claiming to be his son.
Peter Sloan insists the 'Star Trek' actor is his dad after he had a brief fling with his mother, late Canadian actress Kathy McNeil, who gave him up for adoption aged five, but the 85-year-old star insists he is nothing to do with the radio host.
The 59 year old has demanded William to have a DNA test, stop saying he isn't his dad and the lawsuit claims the actor "admitted he was the plaintiff's father", according to New York Post's Page Six column.
Peter claims in the lawsuit, filed in Florida, that William's comment came when they met on the set of police drama TV series 'T.J. Hooker', but shortly afterwards a representative for the star contacted him and said he was "totally denying paternity at this point".
He alleges the rep also told him: "Don't go public ... [as it] could be horrendous for [William]."
Peter added to the publication: "I am William Shatner's son, and I just wish he would acknowledge me."
But a rep for William insisted: "Mr. Shatner has three lovely daughters, but no sons ... Mr. Shatner is aware of the lawsuit, but there's nothing there because he isn't his father."
William's lawyer Erik Hyman has also been in touch with Peter after he registered the internet domain petershatner.com, started hosting a radio show on CBS under the name Peter Shatner in 2011 and turned up to see William at a meet-and-greet.
The attorney wrote to Peter, telling him that William is "not interested" in talking over his claims.
He wrote: "Bill ... confirmed to me once again that he is not your father. There have been many people over the years who have claimed to be his children or other relatives.
"He is an incredibly busy, 80-year-old man, and is not interested in spending time discussing this issue with you."
Last month, William - who has three daughters, Leslie, 57, Lisabeth, 55, and 51-year-old Melanie from his first marriage to Gloria Rand - insisted he didn't have any regrets about his life.
Asked what he would change about his life, he said: "Nothing. I've got a beautiful wife, three beautiful children and I've raised a large amount of money for charity [a 2,400-mile motorbike ride across country for the American Legion].
"Everything that has gone on before has made me one of the luckiest men on Earth."
