Bryan Singer, the director behind multiple X-Men movies, was accused in a new lawsuit of allegedly sexually assaulting a 17-year-old boy in 2003, according to The New York Times.

Per the Times, Cesar Sanchez-Guzman claims in the lawsuit that he met Singer at a Seattle-area yacht party in 2003. The lawsuit alleges that Singer offered to give Sanchez-Guzman, then 17, a tour of the boat, and that when they got into a bedroom, Singer sexually assaulted him.

The suit further alleges that Singer told the young man no one would believe him if he came forward and that he threatened to ruin Sanchez-Guzman’s reputation if the alleged assault ever became public.

A rep for the director said in a statement to the Times that Singer “categorically denies these allegations and will vehemently defend this lawsuit to the very end.” The statement added: “Once Bryan prevails, he will pursue his own claims for malicious prosecution.”

Singer is the latest in an ongoing torrent of high-powered Hollywood men to have sexual misconduct allegations brought against them, although this isn’t the first time that a sexual assault lawsuit has been brought against the director, who has never been charged or convicted.

Earlier this week, Singer was fired from the upcoming Queen biopicBohemian Rhapsody for reportedly not showing up to set. Singer claims that he needed to travel to be with an ill parent, and denies reports that there had been clashes with the film’s star, Rami Malek.
