Michael Flatley dances with his future wife

Lord of the Dance star Michael Flatley dances with one arm around Niamh O'Brien in this undated photo. They were married on October 14, 2006, after dating for five months; Flatley was 47 years old and O'Brien was 32. The pair first met when both were in the Irish dance spectacular Riverdance in 1993 -- he as a star, she in the dance line. "There was an immediate attraction," according to photo service WENN, "but they only became an item in May of 2006."
