ITS not often I have good news about AMY WINEHOUSE 
 but the troubled singer is slowly starting to win her battle against drug addiction.

The Back To Black star spent her fourth day in rehab yesterday, where she is delighting doctors with her progress.

Especially because she hasnt even tried to do a runner.

For the first time it actually looks like Amy is making an effort to sort herself out.

She was admitted to The Capio Nightingale Hospital in central London after our shocking video showed her smoking deadly crack cocaine in a seedy flat in Bow, East London, at 5am.

Amy has since received a visit from close friend MATT LUCAS and his boyrfriend on Sunday as the Little Britain star showed his support.

A relieved close family friend said last night: Although Amy is still taking each day at a time she has done the hardest thing in the world by going into rehab.

She has been ill and is withdrawing but at least she is sticking with it as she detoxes.

With her familys support we are hopeful that there is finally light at the end of the tunnel as she weans herself off drugs.

She will stay in rehab for as long as it takes even if it is three or four weeks.

Nobody is saying it will be easy, but things are looking good at the moment and doctors are encouraged.

The family friend also slammed Amys jailed husband BLAKE FIELDER-CIVIL for saying he fears her habits could kill her within three months.

Blake is in Pentonville Prison in London awaiting trial over trial-fixing allegations and GBH.

The friend went on: That is a complete joke. Before Amy met Blake she never took any Class A drugs.

It is him who started her off on crack and heroin.

She has gone into rehab so she lives to see her thirties, forties and fifties.

It would destroy her to read his comments. Thankfully where she is means Amy has not got any contact with Blake at the moment.

She has agreed to pay all his legal costs which could run into £300,000 or £400,000 when his trial begins.

Blakes family never offered to pay any of the money

But with his comments I am not sure if that arrangement will still exist.

The truth is she is doing fine and needs support from people, not somebody knocking her.

Doctors say it can take a few visits for patients to stay clean when they leave and Amy could easily still take a bit when she comes out.

The classic way is for them to start doing drugs again then end up having to go back into rehab afterwards.

Nobody is sure what will happen but we are all keeping our fingers crossed that this stint does her good.

Amy has still got a long way to go but this is the most encouraging news about her drugs battle Ive heard.
