As the second anniversary of singer Amy Winehouse’s death approaches next month, her brother is opening up about his sister’s passing for the first time.

Rolling Stone magazine reports that Alex Winehouse, who was four years older then his famous sibling, reveals in a new interview with the Guardian what is was like growing up her, provides insight on her personal struggles and promotes a new exhibit that honors the late British artist.

In the Guardian interview, Alex talks about his sister as any brother typically would, starting out by saying how she “was annoying, frustrating, a pain in the bum.” However, he discussed how he had a close relationship with her, reminiscing about how “incredibly generous” and caring she was, especially when it came to her family and friends.

“She’d do anything for anyone, she really would,” he said. “She was loyal – as a sister, daughter and friend. She was probably the most loyal friend to people I’ve ever known.”

Despite her positive attributes, there was a dark side to her as she struggled with addictions to drugs and alcohol, of which the latter ultimately led to her death. The “Rehab” singer died of alcohol poisoning at the age of 27, however Alex believes an eating disorder that Amy developed during her early teens and lasted for the rest of her life was just as detrimental to her downfall, if not more.

“She suffered from bulimia very badly,” he said. “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.” He explains how the eating disorder left Amy weak and made her more susceptible to other negative influences.

Alex talks about one incident of how her destructive behavior affected him, explaining that Amy got drunk and ruined his 30th birthday party.

Of the event he said, “I was furious. She was head-butting people, but she’s only little, she’s tiny – so it’s like swatting away a fly, but it was no good. I had a go at her, threw out some home truths. She knew how I felt and she didn’t scream back at me.”

Regardless of Amy’s troubles, Alex says he and the family are committed to honoring her memory and preventing others from suffering from the same fate as Amy. In addition to setting up The Amy Winehouse Foundation, which helps young individuals who have drug and alcohol problems, an exhibit called “Amy Winehouse: A Family Portrait” will be on display from July 3 through September 15 at London’s Jewish Museum. The exhibit will feature things such as artifacts from her life, clothing and photographs.
