Hopes were high last night that singing sensation Amy Winehouse will be well enough to perform her pre-Christmas gig in Belfast.
The Mercury-prize nominee is due to play the Waterfront Hall on December 3.
Fans of the troubled soul star were confident that the party-loving Rehab singer, who was admitted to hospital suffering "severe exhaustion" would be back on her feet by then.
Last night concert promoters Wonderland refused to comment on the possibility of 23-year-old Amy cancelling the gig, despite her reputation for no-shows.
She has recently pulled out of a number of high-profile performances including the Oxygen festival near Dublin when thousands of fans were disappointed.
Amy also pulled out of T in the Park in Scotland - citing "exhaustion" - and Liverpool's Summer Pops event.
Last night she cancelled a show in Oslo, Norway at the Oya music festival and will miss further performances in Norway and Denmark scheduled for this week.
Yesterday a spokesman for Island Records said: "Amy Winehouse was admitted to University College London Hospital this morning suffering from severe exhaustion.
"Amy was discharged from hospital this afternoon and has been advised to take complete rest. Scheduled performances in Norway and Denmark this week have been cancelled."
Oya Festival organisers said Winehouse cancelled with no explanation. A message on their website said: "The news of the cancellation came abruptly and surprisingly upon us a little before 1pm. Winehouse's large crew arrived and her backing band had just finished their soundcheck when we were notified."
The singer, whose biggest hit is Rehab, has a reputation for drinking heavily.
