George Michael is canceling several concerts while he recovers from a nasty bout of pneumonia.
"George was recently forced to postponed tour dates in Vienna and Strasbourg under doctor’s orders after being diagnosed with pneumonia. He is currently receiving treatment," says a statement on his website.
The 48-year-old "Wham!" singer is currently touring Europe as part of his "Symphonica Tour" -- which is expected to continue into 2012.
