Singer George Michael has pneumonia

The 48-year-old former Wham star has cancelled a string of appearances on his Symphonica tour while he is being treated.

Michael’s publicist Connie Filippello said in a statement that he had been “diagnosed with pneumonia and he is currently receiving treatment”.

Austria’s state broadcaster reported that he was being treated in Vienna’s AKH hospital.

Michael was due to appear at the Stadthalle in Vienna on Monday but he cancelled two hours before the concert was due to start.

He was due to perform in Strasbourg last night and at Cardiff’s Motorpoint Arena on Saturday and Sunday but those shows have all been postponed “due to his ongoing illness”, a statement on the singer’s official website said.

Michael has sold more than 100m records worldwide.

Ticketholders have been told that concerts will be rescheduled and Ms Filippello said that new dates “will be provided when available”.
