LONDON, Aug. 28, 2007 — -- In a live radio interview broadcast throughout Britain today, Amy Winehouse's parents-in-law urged fans not to buy the singer's records as a signal to their son and his troubled wife to stop using drugs.
Giles and Georgette Fielder-Civil, parents of Blake Fielder-Civil, Winehouse's husband of nearly four months, also said Winehouse should not be given any awards or nominated for any prizes until she has kicked the habit.
Fans should make it clear to Winehouse that "her addiction and behavior are not acceptable," Giles Fielder-Civil said.
Winehouse, nearly as famous for her heavy drinking as her husky, soulful voice and black beehive hair, made headlines last month when she collapsed in a London street, apparently from an overdose of heroin, ecstasy, cocaine and alcohol.
In seeming contradiction with the lyrics of her hit song "Rehab," in which she sings of defying a doctor's order to get treatment for her addictions, Winehouse and her husband checked themselves into a rehabilitation center after the incident.
But just days later, Winehouse and Fielder-Civil left the clinic and Winehouse canceled her August performances.
That night, the pair were spotted entering a London pub.
Georgette Fielder-Civil said she believes her son and daughter-in-law are using crack, cocaine and heroin, and should be stopped before it's too late.
"I think they both need to get medical help, before one of them, if not both of them, will eventually die," she said in an especially emotional part of the nearly 22-minute-long interview on BBC Radio Five Live's morning show.
Just last week, shocking images of a bruised and bloodied Winehouse appeared in the British press. Her husband, with deep red scratches on his face and neck, was at her side.
The couple denied that the pictures, which showed Winehouse wearing blood-stained ballet slippers and bandages on her arms, were evidence of a physical fight, despite widespread rumors.
British police said no charges were filed.
Fielder-Civil's parents described their desperate plea this morning as a last-ditch attempt to force the couple to face their deteriorating health situation head-on.
They're in "abject denial," Giles Fielder-Civil told radio host Victoria Derbyshire. "They don't see themselves as having a problem, and they're quite aggressive in their defense of themselves."
Robert Poznanovich, 51, co-founder and CEO of Addiction Intervention Resources, an international consulting agency that helps families deal with addiction, said the Fielder-Civils' decision to talk about a family crisis on live radio was a sign of desperation.
"They probably view this as though they're battling for their son and daughter-in-law's life," Poznanovich told ABC News in a telephone interview. "Their fear of doing nothing is greater than their fear of doing something."
Poznanovich said he applauded the Fielder-Civils for their openness. "The greatest form of enabling is silence," he said.
Just moments after the Fielder-Civils' interview aired this morning, the same radio program received a call from Winehouse's father, Mitch Winehouse.
"It's a horrible situation," Winehouse said, his tone urgent, and sometimes sounding on the brink of tears. "Our family and Blake's family are living through hell."
But Mitch Winehouse said he doubted asking fans not to buy his daughter's records would help the situation.
"Will it do any good, no, it won't," he said. "It won't send any message to Amy at all."
"At some point they're going to hit rock bottom," Winehouse continued. "And at that point they will say, 'Listen, I don't want to do this anymore. I've got responsibilities, I've got a family that loves us, and, you know, I don't want to hurt them anymore.'"
