Amy Winehouse has reportedly been filmed snorting cocaine in a pub in London.
The footage, published by the News of the World newspaper, was apparently shot last month, as the singer played a DJ set at the Monarch in Camden.
Winehouse, who is dressed in a pink shirt and blue jean hot pants, can be seen crouching behind the DJ stand in the film.
The newspaper then alleges that the star snorts a line of the drug off a CD case.
The publication of the footage comes less than a week after it emerged Winehouse is to check herself in to a rehab centre in Suffolk.
The Focus 12 clinic, which also treated comedian Russell Brand, is a short drive from the prison where her husband, Blake Fielder-Civil, is serving a 27-month sentence for assault and perverting the course of justice.
Responding to the footage yesterday, Fielder-Civil’s mother, Georgette, said: “Prison will do Amy far more good than Rehab.”
“I’m shocked by the video. When I look at Amy I think: ‘For Christ’s sake, just get a grip of yourself’. Enough is enough.”
Winehouse was bailed by police earlier this year over a video which apparently showed her smoking crack-cocaine.
Police later confirmed that Winehouse would face no charges over the footage.
