Blake Fielder-Civil has been swapping his wife Amy Winehouse’s autograph in exchange for heroin while incarcerated at London’s Pentonville Prison.

According to The Sun: Blake has traded autographed pictures of his Grammy Award-winning spouse to fellow inmates who hope to sell them on eBay. He receives a “joey” – British slang for a hit of heroin- for the flicks.

“Blake has to pay for his gear somehow – and he has no qualms about cashing in on his wife’s fame. He’ll take orders from other inmates then ask Amy to bring in signed photos of herself during visits. He usually gets her to write a little personalised note to make it look authentic. Once he’s back on the wing he’ll swap these for Joeys.

“The boys think they’ll get a few quid for them on eBay. It’s not clear whether she knows exactly what’s going on… but she must find it strange that all these so-called prison hardmen have suddenly become starstruck Amy Winehouse fans.”
