Amy Winehouse’s husband writes threatening letter to her dad?

Amy Winehouse’s husband Blake Fielder-Civil has reportedly sent an abusive letter filled to violent threats to her dad, Mitch Winehouse.

The two men are said to have been at loggerheads over most of the last couple of years as Mitch blames Blake for Amy’s drug problems but a source close to former taxi driver Mitch told the Sun that the letter is new low between the pair.

The source explained: “I could hear Mitch physically shaking when he phoned to tell me about the letter.

“He couldn’t even bring himself to read it out loud as it was just too sickening. But he told me that Blake described graphic scenes from a horror movie, in which Mitch is the victim.

“Part of Mitch wants to pursue this further with the police, maybe even taking out a restraining order. But then he is worried about it all driving a wedge between him and Amy.”

Blake is currently in prison, serving his sentence for assault and perverting the course of justice. He is expected to be released at the end of the year.
