Amy Winehouse is currently undergoing more tests at a London hospital after suffering from a fainting spell on Sunday, her rep announced.
"Amy has undergone more scans and tests today and we are awaiting the verdict of her doctors," her rep says.
Results permitting, the troubled 24-year-old is still planning to perform two concerts as scheduled next week.
"At present, she still intends to perform at her two scheduled dates next week," the statement continues. "However, the decision will be made entirely on the advice of her doctors and in her best interests."
A five-time Grammy winner, Amy, who was hospitalized last summer for "severe exhaustion," was admitted to the hospital earlier this week by her father Mitch after fainting at home.
After initial tests came back inconclusive, the soul singer was advised to stay longer.
Next week, Amy was scheduled to play a birthday concert on June 27 for Nelson Mandela in London’s Hyde Park.
