Amy Winehouse has reportedly kicked hubby Blake Fielder-Civil to the curb after learning he had traded her in for a German model.

The singer told a UK publication that their relationship is over because it was only ever about sex, drugs and rock 'n' roll.

And now that Blake is said to be spending time with Sophie Schandorff, she is ready to throw in the towel on their on/off four-year relationship.

Amy told The News of the World, "It's over. There's no way back for us now. It was never going to last. We were only together for sex."

A pal of Amy's adds, "Just like they were with drugs, they pushed themselves to the limit.

"And the pair of them were into some real kinky stuff, not just the usual bondage and sex games but really gross stuff you couldn't mention in a newspaper."

Amy's admission ends months of speculation that her marriage was on the rocks, after she repeatedly failed to visit her husband in jail and later rehab.
