George Michael in Vienna Hospital
Connie Filippello said Wednesday that Michael's upcoming tours in Vienna, Strasbourg, France, and Cardiff, Wales, have been postponed as a result and will be rescheduled.
Her statement said the singer has been "diagnosed with pneumonia and he is currently receiving treatment."
Austrian state broadcaster says that is happening at Vienna's AKH hospital. A woman who answered the phone there refused to comment due to privacy rules. She also did not give her name.
Michael, 48, canceled his planned Vienna concert on Monday two hours before it was due to start.
