Amy Winehouse's incarcerated husband Blake Fielder-Civil has reportedly suffered a near drug overdose while staying at Pentonville prison in London. Fielder-Civil is alleged to have taken a drug in which he thought was heroin, according to a Sunday newspaper. He was immediately rushed to the prison hospital wing where staff ressuitated him.

A source told the News Of The World, “He's being very stupid. It's only because everyone reacted so quickly that this dodgy gear didn't do long-term harm.

“This was a close call, but he might not be so lucky next time.

"If he carries on taking so many drugs, he'll end up dead before long." The source added.

Civil-Fielder is awaiting trial on GBH and perverting the course of justice charges.
