Lily Allen has come foward with an account of alleged sexual assault by an unnamed music industry executive that she has worked with. In an interview with the Guardian Weekend magazine that was previewed online today, she details the alleged incident that occurred in Los Angeles.

Allen claims that after she got “smashed” at a party, the man settled her in his hotel room and left her to sleep. Then, she alleges, “I woke up at 5am because I could feel someone next to me pressing their naked body against my back. I was naked, too. I could feel someone trying to put their penis inside my vagina and slapping my arse as if I were a stripper in a club. I moved away as quickly as possible and jumped out of the bed, full of alarm. I found my clothes quickly and ran out of his room and into my own.”

After the alleged incident, she claims that she did not immediately report it because she feared being labeled “hysterical” and a “difficult woman.” After she returned from Los Angeles to London, she says she signed an affidavit documenting her recollection of events. “I wanted it on record that I’d been sexually abused by someone I worked with,” she says.

Allen says she was later offered a gig promoted by Radio 1 where one of the executive’s artists would have been present, but turned it down because she didn’t want to encounter the man again. She claims she was then “punished by Radio 1, with no airplay for my next single, ‘Trigger Bang.’” She continues, “I just couldn’t tell them why I couldn’t take the slot.” Guardian Weekend’s full interview with Allen will be published tomorrow (Saturday).

Allen also addresses the alleged assault in her upcoming memoir, My Thoughts Exactly, which is due out September 20 in the U.K. and December 20 in the United States. According to the interview with Guardian Weekend, she wanted to name her alleged assaulter in the book, but did not after receiving legal advice from her publisher. Pitchfork has reached out to representatives for Lily Allen for further comment.
