William Shatner is being sued for $170 million by a man who claims to be his son.

According to New York Post, Peter Sloan (or Peter Shatner as he prefers to be called) filed paperwork in Florida Tuesdaydemanding the Star Trek star take a paternity test to prove he's Sloan's biological father.

Sloan's mother is the late Canadian actress Kathy McNeil, who Sloan claims had a brief affair with Shatner that resulted in Sloan's conception. McNeil gave Sloan, now 59, up for adoption five days after he was born.

Sloan is a Canadian radio host who claims that Shatner admitted to being his father when the two met on the set of Shatner's TV series T.J. Hooker in 1984. Since that meeting, Shatner has publicly denied being Sloan's father. The younger man also says that Shatner's team shut down his Twitter account and that Shatner's social media manager, "posted malicious, libelous and slanderous statements about the Plaintiff on Facebook and Twitter."

In addition to the paternity test, Sloan also wants financial retribution for Shatner's alleged attempt to shut down Sloan's use of Shatner as his last name. The lawsuit asks for $30 million in compensatory damages, $90 million in punitive damages and $50 million for pain and suffering.

Shatner responded to Sloan's lawsuit with a tweet that once again denies being his father. "My children are my life. I have three kids in total; Leslie, Lisabeth & Melanie. They are my reason to get up & live each day to the fullest," the actor writes.
