LOS ANGELES - Police in Los Angeles announced Wednesday they are investigating a rape allegation made against British "Gossip Girl" actor Ed Westwick.

Los Angeles Police Department official Drake Madison said there was an "ongoing investigation" taking place, after actress Kristina Cohen accused him of rape Tuesday in a Facebook post.

"I do not know this woman. I have never forced myself in any manner, on any woman. I certainly have never committed rape," Westwick, 30, wrote on Twitter.

Cohen alleged Westwick raped her three years ago at his house, shortly after propositioning her and a producer she was dating.

Cohen - who has played roles in series such as "Californication" and "The Middle" - added the producer blamed her and suggested accusing Westwick would ruin her career. - AFP
