Blake Fielder-Civil is concerned about his wife's bulimia condition and is urging her to fight it.
Blake, who is currently in jail, is anxious to save his troubled wife and after seeing her skinny frame on one of her weekly visits to the prison, he has requested her to put on weight.
"You've got to beat bulimia or it could kill you. I'm really concerned about you. You are far too thin", News of the World quoted him, as telling Winehouse.
Blake was extremely distressed when he saw his undernourished wife, especially since he had put on 11pounds himself.
"For the first time in months I've been eating three square meals a day. I feel so much better. But you are taking drugs, not eating and now you are fainting," he told Amy.
"You have got to eat properly and stop sticking your finger down your throat. Bulimia is taking a terrible toll on you", he added.
