Blake Fielder-Civil's mother thinks he needs to accept "his portion of blame" for Amy Winehouse's death.
Georgette Civil - whose son got divorced from Winehouse in 2009 after two turbulent years of marriage - thinks Blake, who is currently serving 32 months in prison for burglary and possession of an imitation firearm, needed to take responsibility for the late singer's problems with drug abuse.
In an interview with UK TV show Daybreak, she said: "I think he has to take his portion of blame.
"I can't say whether or not Amy did drugs prior to meeting Blake, I can't. I think that's something that nobody will ever really know. But yes, in my heart I think that Blake has to take a portion of blame."
After Winehouse was found dead in her home in Camden, north London, on Saturday at the age of just 27, Georgette voiced her fears that heroin addict Blake would "kill himself" when he found out about the tragedy.
