Winehouse was apparently 'beyond help' when paramedics arrived, according to Sky sources.
Sources have also claimed Winehouse's death was due to a drug overdose.
Two ambulance crews arrived at the scene within five minutes and a paramedic on a bicycle also attended, according to a spokeswoman.

In a statement, the Metropolitan Police 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.

'Enquiries continue into the circumstances of the death. At this early stage it is being treated as unexplained.’
A Metropolitan Police spokesperson said in a press conference this evening that no cause of death had yet been confirmed.
He said: 'I am aware of reports of a suspected drugs overdose, but I would like to reremphaise that no post-mortem has yet taken place and it would be inapproporaite to speculate on the cause of death.

A spokesman for the late singer said: 'Everyone involved with Amy is shocked and devastated.

A Scotland Yard spokesman is quoted by the website as saying: 'The postmortem has not been scheduled yet but it is unlikely to take place before tomorrow.
'In the case of a murder it can be done within hours but this is not the case so tomorrow or even Monday is more likely in these circumstances.'
Mourning: Floral tributes are left outside Amy's house as news breaks of her death
Winehouse had been seen with her goddaughter Dionne Bromfield earlier this week as the teenager took to the stage at the iTunes festival.
She refused to join in for Mama Said, but did support the 14-year-old with a few dance moves before urging the crowd to buy Dionne's new album Good For The Soul.
A source said: 'Amy staggered onstage and grabbed the mic to beg the crowd to buy her protege’s new album.'
Winehouse's appearance at the concert came after she cancelled her European tour following a disastrous performance in June when she stumbled onto the stage in Belgrade and gave an incoherent performance appearing very disorientated and removed from reality.
