Winehouse shot to fame in 2006 with the album "Back to Black," whose blend of jazz, soul, rock and classic pop was a global hit. It won five Grammys and made Winehouse ï¿½ with her black beehive hairdo and old-fashioned sailor tattoos ï¿½ one of music's most recognizable stars. But her personal life, with its drug and alcohol abuse, eating disorders and destructive relationships, soon took over her career. Police confirmed that a 27-year-old female was pronounced dead at the home in Camden Square northern London; the cause of death was not immediately known. London Ambulance Services said Winehouse had died before the two ambulance crews it sent arrived at the scene.
