Brett Ratner allegedly masturbated in front of a model while in a car with his assistants

Another woman has come forward to accuse Brett Ratner of sexual misconduct. A model, whose identity has not been disclosed, has alleged the movie producer and director masturbated in front of her almost a decade ago.

The model, who is based in New York, told Page Six that the incident occurred after Ratner flew her to Los Angeles for a photoshoot in 2008.

Ratner allegedly committed the act when he and the model along with his two assistants were travelling to the location of the photoshoot in a chauffeur-driven car.

"I put my hands over my eyes and said, 'Stop. That's disgusting.' But he wouldn't stop. As he is finishing, his assistant in the front seat hands him tissues," the model is quoted as telling the news website.

The model added that she "was really uncomfortable" when they arrived at the location.

"I never worked with him again, and I never got into a car with him again," she said.

Two of her friends corroborated the story, saying that the model told them about the incident shortly after it occurred.

The model did not go to the police because she thought no crime was committed.

"It was just really weird," she said.

Following the allegations, Ratner's attorney, Lynda Goldman, told the website that her "client categorically denies this outrageous story".

In an email, two of Ratner's assistants who were reportedly inside the car told the news website that they saw nothing inappropriate.

The disclosure comes just a day after actress Ellen Page accused Ratner of shaming her on the sets of X Men.

Ratner allegedly told a woman 10 years senior to Page to have sex with the latter to confirm if she was gay.

Ratner allegedly said, "You should f**k her to make her realise she's gay", according to Page, who was 18 years old at the time of the incident.
