London - Amy Winehouse's brother claims she died of bulimia.
The late singer passed away in 2011 due to accidental alcohol poisoning and Alex insisted her battle with the eating disorder - which usually involves vomiting to get rid of unwanted food -contributed to her early death.
He told The Observer Magazine: "She suffered from bulimia very badly.
That's not, like, a revelation - you knew just by looking at her.
"She would have died eventually, the way she was going, but what really killed her was the bulimia ... Absolutely terrible ... I think that it left her weaker and more susceptible.
