The 'Rehab' singer - Amy Winehouse was killed by booze not drugs, say family sources.
Her family says toxicology results showed the presence of alcohol but no illegal drugs in her body when she died, the Sun reported.
The claims may be heard at St Pancras Coroner's Court in central London, where Winehouse's distraught dad Mitch and mum Janis are expected to attend an enquiry into her death.
The 'Rehab' singer was found dead in bed at her 2.3million pounds home in Camden, North London, in July.
Cabbie Mitch, 60, has earlier said that his daughter had made a "fantastic recovery" from drug addiction and had not drunk booze for three weeks.
And her family sources have also suggested that her death could have been caused by sudden alcohol withdrawal after she ignored doctors' warnings to cut down gradually.
