George Michael has pulled the plug on the rest of his tour as he battles "severe" pneumonia.
The singer, who is being treated in hospital in Vienna, Austria, has been told by doctors to take "complete rest".
The star, who has been diagnosed with "community acquired pneumonia", was due to play UK shows on his Symphonica tour until the week before Christmas.
His publicist said today: "He is receiving excellent medical care; he is responding to treatment and slowly improving."
Specialists in Vienna issued a statement saying: "From the current point of view, the time until recovery cannot be estimated, but he will not be able to perform the rest of the tour.
"Besides medical treatment, complete rest and peace and quiet are mandatory."
Promoters are working to rearrange the postponed dates "at the earliest opportunity".
