Winehouse 'still hopes to sing'

Winehouse was at home in London when the incident happened
Amy Winehouse still hopes to perform at the forthcoming Glastonbury Festival and Nelson Mandela concert
despite her ongoing treatment in hospital.
The 24-year-old Rehab singer is undergoing tests after fainting at home on Monday afternoon.
Winehouse is on the bill at the Nelson Mandela gig in London's Hyde Park on 27 June

and at Glastonbury the next day.
"At present she still intends to perform at her two scheduled dates next week

" her spokesperson told the BBC.
"However the decision will be made entirely on the advice of her doctors and in her best interests."
"Amy has undergone more scans and tests today and we are awaiting the verdict of her doctors."
There have long been concerns about Winehouse's health.
Last year

she was admitted to a hospital in London suffering from "severe exhaustion"

and there were reports that she was being treated in a rehabilitation clinic. Following a succession of cancelled gigs

the singer's father spoke out about her drug use. In August 2007

Mitch Winehouse told BBC Radio 5 Live his daughter and her husband Blake Fielder-Civil had "serious problems"

but said neither was in "imminent danger of death".
