Michael Flatley is critically ill with a mystery infection that is said to be attacking his entire body. The 48-year-old `Riverdance’ star is being treated in hospital after falling ill at his London home two weeks ago. His dancer wife, Niamh o’Brien, (32) who is four months pregnant, is at his bedside. They married last month. A source says there is mounting concern among his friends, adding, “Michael is a very fit man but he is in the fight of his life. At first no one realised how serious it was but it soon became obvious that he is really ill.” All 20 European dates for his latest production, Celtic Tiger, have been cancelled. [17 November 2006]
