Amy Winehouse has started using cocaine, ecstasy, and cannabis, claim her pals.
The singer, 24, spent 2 weeks in rehab last month - and has been continuing her treatment - but now she's said to have relapsed because she's missing her husband so much.
Blake Fielder-Civil, 25, is currently being held in Pentonville Prison on charges of GBH and attempting to fix a trial.
'Amy has been up and down in a way she never was before,' a pal tells The Sun.
'One minute she'll be fine, the next she'll be in a heap on the floor, screaming she can't go on. She feels that rehab is turning her into some sort of zombie with no emotion.'
On the first night at London's Capio Nightingale Hospital on 24 January, Amy's said to have begged a friend to take her in some drugs.
'After that she did not take anything for a week to 10 days. But that was just about trying to get her to the Grammys. Now we're back to the dangerous levels of before.'
But Amy's representative has denied that the star's lost her way again.
'You can clearly see she's looking well, far better than if she was taking drugs,' Amy's spokesman tells the Daily Star. 'She's getting round-the-clock medical attention as well.'
