Rehab singing star Amy Winehouse has been admitted to the hospital again after an argument with husband Blake Fielder-Civil allegedly sparked a drinking and drugs binge. Amy collapsed and was taken to a private clinic in London England after allegedly ingesting a toxic cocktail of illegal substances and booze. According to Britain's The Sun newspaper, Winehouse became embroiled in a screaming match with Fielder-Civil on Sunday, just a day before he lost an appeal against his 27-month prison sentence relation to an attack on a pub landlord at a London court. A source tells the publication, "They had a screaming row. She was beside herself after the call -- and she just totally lost it."The singer's spokesperson confirmed the star had been kept in hospital for observation on Sunday, but denied it was due to the singer's drug habit, insisting she "had a bad reaction to the combination of medication she has currently been prescribed."The new drama in Winehouse's battle with her addictions comes just days after the star admitted her marriage to Fielder-Civil was over, reportedly stating their union had been based purely on sex. She told Britain's News of the World newspaper, "It's over. There's no way back for us now. It was never going to last. We were only together for sex. I fancied him like mad, like no one else I've ever known. But it's not enough, is it?"Reports of a split between the pair have circled since Fielder-Civil was released from prison earlier this month after serving almost a year behind bars. As part of his early release deal, he checked into a rehabilitation facility in Surrey, south east England, but Winehouse has still yet to visit her husband.
