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.
An ambulance could be seen parked beneath the trees outside her London home, and the whole street was cordoned off by police tape. Officers kept onlookers away from the scene.
Last month, Winehouse canceled her European comeback tour after she swayed and slurred her way through barely recognizable songs in her first show in the Serbian capital of Belgrade. Booed and jeered off stage, she flew home and her management said she would take time off to recover.
