Soul singer Amy Winehouse has developed the lung condition emphysema and has been warned by doctors that she will die if she continues smoking drugs, her father said in an interview on Sunday.

Mitch Winehouse said the incurable illness, which leaves sufferers struggling for breath, was diagnosed when his daughter had series of health checks in hospital.

“The doctors have told her if she goes back to smoking drugs it won’t just ruin her voice, it will kill her,” he was quoted as saying in the Sunday Mirror. “The doctors have said that if she had continued the way she was going she could have ended up an invalid — she wouldn’t have been able to breathe.”

He added: “She’s got emphysema. It’s in its early stages, but had it gone on for another month they painted a very vivid picture of her sitting there like an old person with a mask on her face struggling to breathe.

“With smoking the crack cocaine and the cigarettes, her lungs are all gunked up. There are nodules around the chest and dark marks. She’s got 70 percent lung capacity.”

He added that a spell in hospital last week and renewed treatment for her well-publicized drug addiction had offered a ray of hope for his 24-year-old daughter.

“If she doesn’t go back to drugs, then she can lead this magnificent life,” he said. “We are praying that that’s what Amy really wants. She seems resolute.”

He called on drug dealers to help her recovery by refusing to supply her with crack cocaine.

There is no medical reason why she shouldn’t be able to perform at the Glastonbury Festival next weekend, he added. In the past, work has helped to keep her away from drugs.

THE British singer has revealed a new statement regarding her involvements on “Quantum of Solace” movie soundtrack claiming that she has written a new song for it.

In other news, Amy herself recently has just won an award at the Ivor Novello. The singer managed to take home the award for Best Song Musically and Lyrically for her single “Love Is A Losing Game”.

Amy Winehouse has confirmed she is to play T In The Park 2008, after cancelling her appearance at last year’s festival.

The singer will perform on the Main Stage on July 13 prior to sets by Kings of Leon and REM.

Festival organizer Geoff Ellis said: “It’s always been the intention to have Amy come to play T In The Park after what happened last year.”
