Amy Winehouse, 27, was discovered at her apartment in north London by emergency services at around 3.54pm this afternoon, according to sources.
A police statement said: “Police were called by London Ambulance Service to an address in Camden Square NW1 shortly before 16.05hrs today, Saturday 23 July, following reports of a woman found deceased.
“On arrival officers found the body of a 27-year-old female who was pronounced dead at the scene.
“Enquiries continue into the circumstances of the death. At this early stage it is being treated as unexplained.”
Amy had recently cancelled all tour dates and engagements after a series of erratic public appearances.
But she appeared with her goddaughter Dionne Bromfield earlier this week at the iTunes festival where she urged the crowd to buy the young singer’s album.
Amy had battled drink and drugs problems throughout her career.
She has had a troubled life which has included various stints in rehab for drug and alcohol addiction.
In an interview in 2008, her mother Janis said she would be unsurprised if her daughter died before her time.
She said: ‘I’ve known for a long time that my daughter has problems. But seeing it on screen rammed it home. I realise my daughter could be dead within the year. We’re watching her kill herself, slowly.
‘I’ve already come to terms with her dead. I’ve steeled myself to ask her what ground she wants to be buried in, which cemetery. Because the drugs will get her if she stays on this road.
‘I look at Heath Ledger and Britney. She’s on their path. It’s like watching a car crash – this person throwing all these gifts away.’
Amy Whinehouse is now on the list of famous people who have died at the age of 27, know as the 27 club.
