Amy Winehouse and Blake Fielder-Civil
Basically the Sid-and-Nancy of the 2000s, she was the British blue-eyed soul star and he was, well, known mostly for being her husband. Both raging addicts, they would often appear in photographs bloody from fights with each other and were known for going out in public high and drunk. Winehouse eventually left Blake to attempt to get her life on track. She sadly died from alcohol intoxication in the summer of 2011.
