A former aspiring actor has told a jury that Harvey Weinstein raped her in a hotel room while she was in an "extremely degrading" relationship with him.
Jessica Mann told Weinstein's New York trial she told no one about what had happened.
"I was so embarrassed," she said, crying on the witness stand as she gave evidence on Friday.
Mann likened Weinstein to "Jekyll and Hyde", saying he could be charming in public but often showed frightening anger when they were alone.
"If he heard the word 'no', it was like a trigger for him," she said.
Weinstein, 67, has pleaded not guilty to raping Mann and to sexually assaulting another woman, Mimi Haleyi.
Since 2017, more than 80 women have accused Weinstein of sexual misconduct.
Weinstein has denied any nonconsensual sex.
Mann, now 34, testified that she met Weinstein in late 2012 or early 2013 at a party in Los Angeles and he told her he was interested in her as an actor.
Weinstein later invited her and her friend to a hotel suite in Los Angeles, Mann testified.
When they arrived, Mann said, Weinstein pulled her into a bedroom, leaving her friend outside.
There, she said, Weinstein told her to sit on the bed and performed oral sex on her. Mann said she pretended to have an orgasm so he would stop.
Weinstein is not charged with a crime in connection with that encounter.
Mann said she then entered into a relationship with Weinstein.
"I entered into what I thought was going to be a real relationship with him and it was extremely degrading from that point on," she said.
When Assistant District Attorney Joan Illuzzi asked her why she stayed in a relationship, Mann, often crying, said there was "no short answer".
"One of the aspects initially was that I had had a sexual encounter (with him)," she said.
"That wasn't something I could undo. That really confused me and hurt me."
She said she engaged in oral sex with Weinstein during the relationship but never had intercourse with him until he raped her at a hotel in Manhattan in 2013.
She said she wrote "flattering" emails during her relationship with Weinstein but that those were driven by fear.
Damon Cheronis, one of Weinstein's lawyers, said in his opening statement that communications between Mann and Weinstein would show that their relationship was entirely consensual.
Weinstein, who produced films including The English Patient and Shakespeare in Love, has denied the allegations.
