THE LORD OF THE DANCE star Michael Flatley will marry NIAMH O BRIEN on Saturday (14OCT06), after dating the dancer for five months. The 47-year-old first met O'Brien, 32, on the set of his RIVERDANCE spectacular 13 years ago (93) and there was an immediate attraction - but they only became an item in May (06). He says, "Fate took a hand and the timing was just right. When you are ready on the inside, you seem to know. "She's been my leading lady for years - we had feelings for each other ever since we met. We've loved each other for years. "She's the most beautiful girl in the world, inside and out. She is exactly what I was hoping my wife would be." Flatley, who is believed to be worth $630 million (GBP350 million) split from ex-fiancee LISA MURPHY late last year (05).
