Amy Winehouse's ex-husband has told of his regret at introducing her to hard drugs - but has claimed her addiction worsened when they were apart.
Blake Fielder-Civil said the two of them spent only four months in which they were taking drugs together as "addicts", due to his spells in jail.
He spoke in an emotional interview as a guest on ITV's Jeremy Kyle Show screened today in which he told of his tears and disbelief when prison staff told him Winehouse had died.
Fielder-Civil - who was married to the singer for two years - said of their heroin and crack use: "Out of maybe a six or seven-year relationship that me and Amy had on and off, there was drug use for about four months together."
He went on: "We used heroin together as addicts for like four months, then I went to jail.
"Then it got a lot worse while I was in jail and then when I came out of jail I was told that if I loved her I'd divorce her and set her free and I did."
The 34-year-old said he had used heroin "three or four times" before she was introduced to the drug.
He said they were in a room in an east London hotel and he had around a £10 batch.
"I was smoking it on foil and she said can I try some and I said... I might have put up a weak resistance - the fact is whatever I said she did end up having some," he said.
"I have to be really sort of conscious about what I say - I don't want to feel like I'm shirking responsibility.
"The fact is what I'm saying is of course I regret it, not just 'cos of the damage it's caused Amy and the loss of life, but the damage to her family but also to my family and also to me.
"You know we've all sort of gone through this addiction."
Winehouse died in July 2011 and a second inquest found last month that she died from accidental alcohol poisoning.
