Blake Fielder-Civil, who pleaded guilty last month to charges of grievous bodily harm (GBH) and perverting the course of justice, had begged Judge David Radford to let him walk free so he could help stop Amy taking drugs.

Blake's attorney, Jeremy Dein QC, said at East London's Snaresbrook Crown Court: "They are very much committed to each other and their ambition is to divorce themselves from hard drugs and not separate themselves from each other.

Amy Winehouse's husband Blake Fielder-Civil has been pictured smoking heroin in his prison cell. The 25-year-old has been photographed inhaling the illegal substance in London's Pentonville prison, despite claiming he is clean of narcotics.

Just hours after the photos were taken, Amy pleaded for her spouse's release as she performed at Nelson Mandela's 90th birthday party.

Blake Fielder-Civil, the husband of British singer Amy Winehouse, has pleaded guilty to charges of assault and attempting to pervert the course of justice.

Fielder-Civil has been in jail since November of 2007, waiting for his trial. During pre-trial arguments last week he admitted that on June 20, 2006 he assaulted James King, the landlord of Macbeth's pub in London.

Amy Winehouse was arrested, questioned and released on bail by police yesterday.

The troubled singer was arrested at 5pm after voluntarily turning herself into Shoreditch police station, in London's Hackney, in connection with the investigation into her husband Blake Fielder-Civil's charge of perverting the course of justice.

Amy Winehouse's husband has been moved to a prison medical unit because doctors are worried he will self-harm.

Blake Fielder-Civil, 25, was arrested outside the north London house he shares with troubled singer Amy last Thursday, and taken into custody.

Amy Winehouse was left "totally distraught" after policemen raided her house and arrested her husband.

The troubled singer - who has battled alcohol and drug addictions - was out collecting a parcel when eight plain-clothes policemen using battering rams and crowbars smashed through the front door of her Camden house at 4:45pm yesterday (08.11.07).
