Ed Westwick has responded to actress Kristina Cohen's claim that he raped her three years ago, categorically denying the story.

On Monday, the 27-year-old actress — who has had small roles in TV and film since 2001 — alleged that the Gossip Girl actor got on top of her and forced her to have sex with him three years ago at his house.

"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," Cohen wrote on Facebook. "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."

Today, the 30-year-old actor denied the allegations with a short Instagram post that said: "I do not know this woman. I have never forced myself in any manner, on any woman. I certainly have never committed rape."

Earlier in her Facebook post, Cohen alleged that a producer she was dating at the time knew Westwick and brought her to the apartment. "I was sexually assaulted three years ago. It was a dark time in my life. ... Even now, I grapple with feelings of guilt. Unfounded worry that in some way I was to blame."

"I was briefly dating a producer who was friends with the actor Ed Westwick," she later continued in the post. "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.' ... 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."
