Lily Allen has quit the music industry.

The 'Fear' singer made the announcement on her new blog - called It's Not Alright, which aims to stop people file sharing music on the internet - revealing she has no plans to release new songs or tour again.

She wrote: "Just so you know, I have not renegotiated my record contract and have no plans to make another record. I do however remain a fan of new music, so this is not some selfish crusade.

"The days of me making money from recording music has been and gone as far as I'm concerned, so I don't stand to profit from legislation. Except future purchases of previously recorded material."

The 24-year-old star is now focusing on her appearance in a London theatre production called 'Reasons to be Pretty', which follows a group of working-class people who are bored with their lives.

It is not the first time Lily has voiced her desire to give up her singing career.

Earlier this month, she said: "I'm not going record and tour again for quite a while.

"I finish up my dates in March and I'll be ready to do something else. I've been on the road for four years and I've given my voice a real run for its money. I'm struggling, so I'm going to try something new.

"The play is about themes close to my heart, about the really damaging cult of beauty among young girls."
