Amy Winehouse is still in hospital while doctors try to figure out why she fainted yesterday, according to her rep.
The troubled star mysteriously collapsed at home in London yesterday and was lucky to be caught by her manager’s assistant before she hit the floor.
The Grammy winner, 24, was rushed to hospital by her father, Mitch, and had a series of tests.
Her rep, Tracy Miller, said yesterday evening that Amy was feeling better, but docs at a private clinic decided to keep her in overnight for observation.
The tests have come back inconclusive and now she has been told to stay for more.
"She’s staying there for the time being," a rep said today. "They are still not quite sure what happened."
Right now, Amy is still expected to play her next scheduled show, a birthday concert for Nelson Mandela in London’s Hyde Park on June 27.
This is the 24-year-old’s second hospitalization in less than a year. Last August, Amy was admitted for "severe exhaustion," causing many to speculate it was a rehab stint.
