Amy Winehouse 'Drowned Her Sorrows In Alcohol' After Blake Fielder Split

Showing rarely-seen footage, insider interviews and shocking revelations, Reelz's new special Amy Winehouse: The Legacy takes an intimate look at the hard and passionate life of the star – from her booming music career, to her personal heartbreaks and eventually to the inner demons that inspired her work and caused her untimely death.

As Winehouse's fame grew, so did speculation in the press about her lifestyle. Her weight was a major focus, as the once-curvy star appeared to drop several dress sizes in 2006.

As OK! has learned, the talented singer once admitted to an interviewer later that year that her new slim frame was due to her cutting back on weed.

During her early twenties, the musician tragically lost her beloved grandmother, which undoubtedly added to her grief as she was just starting to fall into a deadly addiction.

Winehouse later entered a destructive relationship with ex-con Blake Fielder, but at that point her drug-abuse had already gone to far for her to handle.

The singer's ongoing addiction likely stemmed from "a position of pain," says Dr. Peter Hughes in the shocking video, "Because unless you feel pain, you do not become an addict."

Winehouse's troubled relationship with Fielder was, according to various sources, a big catalyst for her destructive behavior.
