Amy Winehouse has declared her marriage to recently-freed husband Blake Fielder-Civil is over after realising their relationship had no future.
Fielder-Civil was released from prison earlier this month after serving almost a year behind bars in relation to an attack on a pub landlord.
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, fuelling rumours their union is in trouble.
Fielder-Civil recently spoke out to dismiss the split claims, while Winehouse has remained unusually quiet about the reports.
However, she has now called time on her 19-month marriage, following reports of Fielder-Civil's close relationship with German model Sophie Schandorff - who has visited him since his jail release.
According to the News of the World, Winehouse said: "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?"
A source adds, "It's a watershed for Amy. She's been up and down for weeks but finally accepts the reality.
"She still loves Blake on many levels but she sees there's no future. She says he wants to be with Sophie - the model who made a play for him during his court appearances, mouthing: 'I love you'.
"Amy knows he's been in touch with her and it's almost like she thinks they're welcome to each other. But she's so furious she won't let the girl's name even be mentioned around her."
The news comes just one day after it was revealed the singer had paid for Fielder-Civil's drug treatment, much to the dismay of her family.
