An anonymous person is suing FX, Netflix and the author of a book that the show "The Assassination of Gianni Versace: American Crime Story" was based on, claiming they were defamed in the show.

The lawsuit was filed anonymously on Tuesday against the two networks, as well as Maureen Orth, who wrote the nonfiction book "Vulgar Favors" and Tom Rob Smith, who wrote every episode of the show.

The lawsuit never mentions the show directly, but it aired on FX and currently streams on Netflix. Orth and Smith are also only connected via the show.

According to court documents obtained by The Blast, the plaintiff (listed only as J. Roe) claims they sued Orth back in 2000 for invasion of privacy and/or defamation. Roe claims the two sides eventually reached a confidential settlement agreement.

Roe claims that Orth violated the confidential settlement agreement with the show.

The lawsuit states that Orth, Smith, Netflix and FX defamed Roe, in part, by "including a false implication that Plaintiff is a chronic abuser of alcohol who consumes alcohol throughout the day."

Roe claims to have reached out to FX to cease and desist "from the ongoing defamation" but claims FX refused.

The suit alleges that Orth "has personal knowledge that the defamatory matter was false, because she fabricated it herself."

Roe is seeking unspecified damages.
