This July, the Jewish Museum in London is exhibiting “Amy Winehouse: A Family Portrait.” To commemorate his sister’s life and work, Alex Winehouse gave his first major interview with The Guardian this past weekend. In it, he alleges that Amy’s death may have had more to do with bulimia than drugs or alcohol:

“She suffered from bulimia very badly,” Winehouse said. “She would have died eventually, the way she was going, but what really killed her was the bulimia. . . I think that it left her weaker and more susceptible. Had she not had an eating disorder, she would have been physically stronger.”

Winehouse goes on to remember his famous sibling from a perspective few, if any saw: as a little sister who, despite the fame and self-destruction that plagued her, still kept her private school uniform stowed away in a box at home and “would have hated” the exhibit that examines the singer’s life through a collection of photographs, personal items and a family genealogy that traces the family’s roots back to Russia and Poland. The exhibit opens July 3rd.
