LILY Allen has claimed she was sexually assaulted by a record industry executive and told how abuse is rife in the music world.

The singer, 33, alleged the man assaulted her when she fell asleep in his hotel room after she got "smashed" at a party.

She said he took her to his room to sleep it off, but she woke up at 5am "because I could feel someone next to me pressing their naked body against my back".

Lily said she "moved away as quickly as possible and jumped out of the bed, full of alarm... and ran out of his room".

The Smile star told the Guardian Weekend Magazine she consulted a lawyer in London and signed an affidavit documenting the incident, because "I wanted it on record that I'd been sexually abused by someone I worked with".

She said she blamed herself for the alleged incident because she had been drinking, and said she did not report it because she thought there was no point in doing so.

Allen described the alleged incident in her memoir, My Thoughts Exactly, which will be published later this month.

She wrote: "What was the crime? Record industry executive didn't rape me. Was I supposed to report someone trying it on? (Answer: yes.)"

The artist told the Guardian she wanted to name the man in the book, but was advised not to on legal grounds by her publisher.

Allen, who has two daughters with ex-husband Sam Cooper, Ethel, six, and Marnie, five, has previously spoken about an alleged assault carried out by someone powerful within the music industry.

The pop star said when she reported it to her representatives, nothing was done about it.

Allen went on to warn the music industry was "rife" with similar incidents, but insiders refuse to speak up about the problem.
