The distraught father of Amy Winehouse has again voiced his fears about the state of his troubled daughter.

Speaking to Sky - in an interview to be broadcast today - Mitch Winehouse raised his concern about his off the rails daughter,  stating that her feared for her life.

In an attempt to help this fragile child, Mitch - a taxi driver from North London - spoke of his anguish at watching his Amy's wild ways.

Worried: Mitch Winehouse revealed his concern for his troubled daughter Amy, fearing she may die if she does not change her ways

He said: 'My biggest fear is that she will die.'

'She wouldn't die form a drug overdose - it would be from emphysema, if she didn't check her behaviour- which she has now done.'

The troubled singer was diagnosed with emphysema- an incurable disease that attacks the lungs - after she collapsed two months ago.

Mitch continued to speak of the effects of her condition.

'She's got a serious health problem and she can't carry on like that.

Even one cigarette will cause physical damage to her' he warned.

'Her emphysema meant that anything inhaled into her lungs is going to cause her a lot more damage.'

'I want people to understand - even if they give her one cigarette, they're causing her harm,' he said.

He added: 'She has a small amount of emphysema in the top of one of her lungs.

'It's negligible, but it could lead to something a lot more serious.'

The interview comes after Amy spent another wild night out and was pictured with a mystery substance up her nose.

The star was DJing at a London pub and looked worse for wear but her father spoke of her gallant effort to make a change and her road to recovery.

'Had she carried on (the way she was last summer) she could have been dead within six months.'

He also praised for Amy's husband Blake Fielder-Civil for his effort and attempt at cleaning up his act.

'He has made a good effort in prison, but when he came out he would need to go straight into rehab.

Fielder-Civil is awaiting sentence on charges of inflicting grievous bodily harm on a pub landlord and also perverting the course of justice.

Mr Winehouse said Amy would be taking a break from live performing.

'From September 6, we're not going to be doing any more work - Amy will be concentrating on writing for the new album.

'She has five contractual gigs between now and then that she has to do. Then she will be relaxing and writing.'
