Gossip Girl actor Ed Westwick has denied Kristina Cohen’s claims that he raped her.

Actress Kristina Cohen, who has appeared in numerous minor TV and movie roles, came forward today claiming that Westwick, 30, best known for playing Chuck Bass on the popular CW series, sexually assaulted her in 2014.

On Monday, Cohen detailed the alleged attack in a Facebook post.

“He held me down and raped me,” she wrote of the alleged incident that she has claimed occurred three years ago at Westwick’s apartment.

“I told him to stop, but he was strong,” she continued. “I fought him off as hard as I could but he grabbed my face in his hands, shaking me, telling me he wanted to fuck me. I was paralysed, terrified. I couldn’t speak, I could no longer move.”

Westwick is currently starring in BBC Two series, White Gold.

However, Westwick has since responded with an Instagram post, claiming not to know Cohen.

He wrote: “I do not know this woman. I have never forced myself in any manner, on any woman. I certainly have never committed rape.”

Cohen’s allegations come after several Hollywood men, including Kevin Spacey and Harvey Weinstein, have been accused of sexual assault against multiple men and women.

Read Cohen’s full alleged account of the incident below: 

“The last month has been incredibly difficult. Like so many women I too have a story of sexual assault, and the outpouring of stories have been both triggering and emotionally exhausting. I’ve gone back and forth over and over again, unsure if I should speak up. If I could speak. And if so, will I be heard?

I was sexually assaulted three years ago. It was a dark time in my life. My mom was dying of cancer and I didn’t have the support system or time to process and deal with the aftermath of the rape. I buried my pain and guilt to make space for the onslaught that came after my mom’s death, just three months later.

Even now, I grapple with feelings of guilt. Unfounded worry that in some way I was to blame. I don’t know where these feelings come from. Social conditioning that everything is always the woman’s fault? That a man’s inability to keep himself off of our bodies is somehow because of us, not him?

I’ve grown considerably in the three years since my assault, so to revisit is painful. To dig in and relive this night in order to accurately share the events, feels like a continued violation. My stomach is in knots, scared as hell to share this publicly, as even fully reconciling with myself has been a tough process.

I was briefly dating a producer who was friends with the actor Ed Westwick. It was this producer who brought me up to Ed’s house where I met Ed for the first time. I wanted to leave when Ed suggested “we should all fuck”. But the producer didn’t want to make Ed 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. Ed suggested I nap in the guest bedroom. The producer said we would stay for just another 20 more minutes to smooth everything over, and then we could leave.

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, his fingers entering my body. 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 fuck me. I was paralyzed, terrified. I couldn’t speak, I could no longer move. He held me down and raped me.

It was a nightmare, and the days following weren’t any better.

The producer put the blame on me, telling me I was an active participant. Telling me that I can’t say anything because Ed will have people come after me, destroy me, and that I could forget about an acting career. Saying there’s no way I can go around saying Ed “raped” me and that I don’t want to be “that girl.”

And for the longest time, I believed him. I didn’t want to be “that girl”.

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.

I’m sickened to see men like Ed respected in such a public way. Interviewed by prestigious platforms such as the Oxford Union Society at Oxford University, where he was honored as one of their “People who Shape our World.” How does this end? Men like Ed using fame and power to rape and intimidate but then continue through the world collecting accolades.

I hope my coming forward will help others to know that they are not alone, that they are not to blame, and it is not their fault. Just as the other women and men coming forward have helped me to realize the same. I hope that my stories and the stories of others help to reset and realign the toxic environments and power imbalances that have created these monsters.”
