Amy Winehouse's train wreck husband Blake Fielder-Civil is being sent back to jail after failing a drug test while in rehab.

The junkie, 26, dashed to his wife's hospital bedside last night from rehab after being told the news. He could now be in jail until early 2010 after breaking the early release terms of his 27-month sentence.

A source said: "Blake did a runner. He turned up in hospital and hell broke loose -- everyone was totally shocked. He was asking Amy to forgive him. As he was going back inside anyway he felt he didn't have much to lose."

Fielder-Civil, who had been at Live Works rehab in Woking, Surrey, planned to hand himself in to cops after an evening with her.

Blake recently apologized for introducing Amy to the drug scenes but with the recent rumors of divorce and now Blake's impending incarceration, it looks like we've seen the last of this ridiculous romance.
