Singer George Michael has pneumonia and has been forced to cancel at least five shows, his website says."He is currently receiving treatment," the brief statement says.
Michael has postponed shows scheduled for this weekend in Cardiff, Wales, after putting off shows earlier this week in Vienna, Austria, and Strasbourg, France.
He was also a no-show for a London concert scheduled for October 26. That concert is now scheduled for May 2, 2012, his website says.
