Cohen wrote that Westwick made a sexual suggestion, and she wanted to leave his home, but the producer didn’t want to make Westwick feel awkward by leaving.
“Ed insisted we stay for dinner. I said I was tired and wanted to leave, trying to get out of what was already an uncomfortable situation,” Cohen wrote.
Cohen claimed that Westwick suggested she retreat to the guest bedroom for a nap and that the producer she was seeing told her they needed to stay for at least another 20 minutes to “smooth everything over.”
“So I went and laid down in the guest room, where I eventually fell asleep. I was woken up abruptly by Ed on top of me,” Cohen wrote, noting that Westwick had begun to touch her inappropriately without her consent. “I told him to stop, but he was strong. I fought him off as hard as I could, but he grabbed my face in his hands, shaking me, telling me he wanted to (have sexual intercourse with) me. I was paralyzed, terrified. I couldn’t speak, I could no longer move. He held me down and raped me,” she wrote.
Cohen said the encounter was a nightmare.
She alleged that the producer made her feel like she was to blame, calling her an “active participant” and said that Westwick would “destroy” her if she came forward with the allegations.
“I now realize the ways in which these men in power prey on women and how this tactic is used so frequently in our industry, and surely, in many others,” Cohen wrote.
Cohen said that she hopes her story will help other victims realize “they are not alone, that they are not to blame, and it is not their fault.”

Westwick took to Twitter with a statement refuting the allegations on Tuesday.
“I do not know this woman. I have never forced myself in any manner, on any woman. I certainly have never committed rape,” he wrote in the captionless tweet.
This allegation comes as several other big names in Hollywood including Harvery Weinstein and Kevin Spacey have been accused of similar allegations.
