80s pop icon George Michael has been forced to cancel a series of upcoming European tour dates after being hospitalized in Vienna, Austria, according to his publicist, Connie Filippello.  The statement indicated that Michael had been diagnosed with pneumonia, and concerts in Vienna, Strasborg, France and Cardiff Wales have been postponed.  The 48 year-old singer reportedly canceled the Vienna performance, scheduled for Monday, just two hours before it was scheduled to begin.  All dates, Filippello says, will be rescheduled.
