Amy Winehouse seen wandering half-dressed

LONDON, Dec. 3 (UPI) -- British singer Amy Winehouse has been photographed wandering the streets of London, wearing only a bra and jeans.

The troubled performer was spotted barefoot and partially dressed leaving a friend's house at 5:45 a.m. Sunday, the Daily Mail said.

Witnesses told the Mail she appeared disorientated and agitated as she wandered around on the pavement for several minutes, despite the cold, then disappeared back inside the house.

Winehouse canceled the remainder of her U.K. concert tour last week, citing health issues and her grief regarding her husband's incarceration as the causes.

The report comes as Georgette Civil, mother of Winehouse's husband, Blake Fielder-Civil, has revealed the singer is ingesting "more drugs than ever" and rarely visiting her husband in prison.

"Amy's having trouble getting her head together about anything right now. It's desperately sad and we're all so worried about her mental and emotional well-being. She needs professional help," Civil said.

"Amy is still using drugs when Blake's in prison. She is using more cocaine and heroin now than ever. She can't stop crying and keeps saying all she wants is peace. She's not eating or sleeping properly and is in pieces," the Mail report said.
