Amy Winehouse cheated on her husband with at least four other men.

Soon-to-be ex-spouse Blake Fielder-Civil claims the 'Back to Black' singer - who admitted adultery in divorce proceedings earlier this month - had trysts with the guys while he was in jail on charges of perverting the course of justice and grievous bodily harm.

Blake said: "She did it time after time. She kept cheating on me, and kept saying sorry. And I kept saying, 'It's alright, I forgive you.'

"The nastier she was, the more in love I became. And she couldn't believe her luck."

Although Blake was devastated by Amy's infidelities, he wasn't surprised because she'd had such a powerful sex drive when they were together.

He added: "My relationship with Amy was very beautiful and intense - and very physical. It was built on sex from day one and was always mind blowing. She is even better at sex than she is at singing."

Amy, 25, was linked to her manager's assistant, 23-year-old Alex Haines, in April last year, then Babyshambles guitarist Mick Whitnall, 41, and Kristian Marr - sometime boyfriend of fashion designer Sadie Frost.

In January this year Amy was said to have had an affair with rugby player Josh Bowman, 21, during her extended break on the Caribbean island of St. Lucia.

Blake, 27, is upset with all of his wife's lovers, because he believes they took advantage of her while she was addicted to drugs and not in full control of her faculties.

He added to Britain's The Sun newspaper: "You should have seen the state of them, especially Alex Haines. I can't even understand why she did it. And I still can't believe Amy is friends with Sadie Frost after she f***ed her boyfriend.

"If I was the person she had these flings with, I may have thought it's not the best idea to sleep with someone who is out of their mind, can barely speak and probably weighs about five stone (70lbs).

"But that's their cross to bear and I think she's just very lonely and has always used her sexuality to make friends."
