The 48-year-old dance impresario has specially purchased a black and silver Rolls Royce Phantom for the occasion, to carry his 32-year-old fiancee to St Patrick’s Church, Fermoy, for the 2pm ceremony.
Ms O’Brien, who is from Co Kildare, will be accompanied by six bridesmaids, including her two sisters Aoibheann and Derval.
Fr Aidan Troy is to conduct the concelebrated ceremony along with local parish administrator, Fr Anthony O’Brien. Afterwards, the couple will return to Flatley’s Georgian mansion, Castlehyde House, where a huge reception is planned.
Flatley’s publicist Geraldine Roche said that six reception rooms in the house were being set aside for the lavish buffet-style banquet. As the mansion, which was acquired by Flatley in 1996, is so large there is no need for marquees to be installed in the grounds.
The Lord of the Dance star has hired a number of private security guards for the event. It is expected that some of the celebrities attending will fly by helicopter directly to Castlehyde House.
Several locals have also been invited, including the Mayor of Fermoy Cllr Tim Carey. Also attending will be Flatley’s near neighbours, including David Magnier, brother of the multi-millionaire horse breeder John.
“Albert Reynolds’ wife, Kathleen, will also be attending. She is old friends with Michael’s father [Michael snr] as they went to school together at Colfadda, Co Sligo,” Ms Roche said. “Mary Harney is also an old friend.”
A number of bands are expected to play at the reception, including the Chieftains, while talented UCC student Sarah Barry has been invited to sing.
The couple will be toasted with bottles of Tsarine champagne, supplied by Bubble Brothers, based at Centre Park Road, Cork.
The couple first met on the set of Riverdance in 1993, but they only got engaged two months ago.
Flatley married Polish make-up artist Beata Dziaba in a register office in 1986. Their divorce became final in 1997 and they had no children. He split from Lisa Murphy last year.
