The countdown is on.

In 142 days, Amy Winehouse's jailed husband, Blake Fielder-Civil, may be released from the slammer, according to a new report out of the UK.

Blake has been told he may be released on December 30 - just in time to shoot up on the outside with the wife and celebrate New Year's!

Of course, he has to stay clean for this to happen.

Word has it he may even be let out next month for a weekend visit if he behaves himself and stays drug-free, but we seriously doubt that.

Regardless, Blake Fielder-Civil's mother, Georgette Fielder-Civil, has pleaded with him to go home to her - not Amy Winehouse.

“We’re hoping his probation officer will advise him to stay with us. If he’s linked with drugs on his weekend visit he will lose the right to come out early,” Georgette said.  “He will be released December 30 if he’s a good boy.”

Blake Fielder-Civil has been in jail for the past year for inflicting grievous bodily harm and perverting the course of justice.

He was given a sentence of 27 months but apparently it may be cut short. Stay tuned as to whether he holds up his end, though.
