Fielder-Civil spent about a year behind bars on charges of assault and attempting to pervert the course of justice. He checked himself into rehab when he was released last month in keeping with the terms of his parole.

"I can confirm he has been recalled," attorney Kate Anderson told People magazine.

Although Anderson declined to say why he was being sent back to jail, a source close to Fielder-Civil told the celebrity weekly he didn't pass a drug test.

Anderson added "the position on recall is that you then serve the remainder of the sentence," which means Fielder-Civil may remain in prison until 2010.

Both Winehouse and Fielder-Civil have publicly stated recently that they plan to end their 18-month marriage. However, Britain's Sun newspaper reported Fielder-Civil escaped from rehab Tuesday night to visit his estranged wife in London where she has been hospitalized for an adverse reaction to medication.

A source told the Sun Fielder-Civil "turned up in hospital and hell broke loose."

"He was asking Amy to forgive him," the insider said.
