Amy Winehouse Still Hospitalized, But Hopes To Perform Next Week

Singer has been under doctor's care since Sunday

Despite being hospitalized since Sunday after a fainting incident at home, troubled British singer Amy Winehouse still plans to perform at a pair of shows in England next week. BBC News reported that the singer, who continues to undergo unspecified tests at a London hospital, is committed to taking the stage next Friday at London's Hyde Park for an all-star concert honoring Nelson Mandela's 90th birthday, and then performing at the Glastonbury Festival the next day.

"At present she still intends to perform at her two scheduled dates next week," a U.K. spokesperson announced on Friday. "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."

Though her spokespeople have not said what is ailing the 24-year-old singer, they denied British tabloid reports that the singer is suffering from tuberculosis. "She had a serious chest infection, and it's routine to check for tuberculosis," a representative told the BBC. "She had a test — it was negative, and she's doing OK. But doctors are still trying [to find] out why she fainted."

Winehouse's U.S. spokesperson, Tracey Miller, said doctors have not yet determined what caused the chest infection, but they do not believe that it is serious. One possibility, she said, is that Winehouse is suffering from a slight case of pneumonia. Miller also said she did not know anything about reports in the British tabloids that Winehouse is suffering from an irregular heartbeat. Amid the medical drama, Miller said the singer — who has battled with drug issues in the past and has drawn concern for her fragile, rail-thin frame — is in "good spirits" and has been surrounded by family as the treatment continues.
