Dance superstar Michael Flatley is reportedly seriously ill in a London hospital suffering from a mystery illness. The Lord Of The Dance star is believed to have been taken ill while rehearsing for the show's forthcoming European tour. He has been admitted to a private hospital in the English capital and all tour dates have been cancelled. Flatley reportedly first visited the hospital two weeks ago. Flatley's spokesperson has refused to comment on his condition - but it is thought to be linked to a facial cancer scare the 49-year-old revealed earlier this year, but believed he had been cured of. Father Aidan Troy, a close friend of Flatley, says of the reports, "I'm shocked. I thought initially it may be exhaustion or stress." Just last month Flatley married his Celtic Tiger leading lady Niamh O'Brien. His wife is understood to be at his hospital bedside.
