If you thought it was going to be quiet for Amy Winehouse now that hubby Blake Fielder-Civil was back behind bars after failing a drug test in rehab, you weren't the only one.

Before being shipped back to jail, Blake broke out of rehab and fled to Amy's side while she was hospitalized after collapsing and according to sources, the on-the-outs couple had a "farewell bonk."

...A source said he persuaded her reluctant inner-circle to give him one hour alone with her on his final night of freedom.

He told Amy, 25, how sexy she looked -- and unlike the line from her hit Rehab, she could not say "No, no, no".

The source added: "It was obvious what went on."

I'll give you minute to erase the image of two junkies humping on a hospital bed. All gone? good. To make things worse, Blake allegedly smuggled drugs into that hospital room and gave Amy one last fix before he turned himself in.

Amy Winehouse's hubby ruined her latest bid to get off drugs -- by taking a fix to her in rehab, claim her pals.

A pal said: "Blake has a lot to answer for. His actions have ruined his wife's efforts to get clean."

Blake is the easy one to blame in this scenario but Amy's family and so-called friends should not let this dude anywhere near her, ever. He should have never been allowed to be alone with her.

But sadly, this isn't the last of Blake, he's now reportedly threatening to release information about the Back to Black singer if she doesn't give him a million pounds.

A pal said: "Blake has a lot to answer for. His actions have ruined his wife's efforts to get clean."

Blake has asked Amy's manager for £1 million to walk away from their marriage and not write a tell-all book about it.

"He's so two-faced. He just wants a pay-off. Money's his driving force."

I think Amy should take her chances with Blake's tell-all. What else could he release that we don't already know?
