More than 500 family and friends have been invited to the service, even though the church can only comfortably accommodate 400.

Majella McLennan was 30 minutes late for the wedding

Kincasslagh is a one-shop, one-pub beauty spot on Donegal's western coast.

The setting is a picture postcard 19th Century church. St Mary's has played a central role in the singer's life.

He was baptised there and it is also where he sung the first notes on his way to stardom.

Hundreds of fans turned up for a glimpse of their idol, with several coach loads arriving from England and Scotland.

The local curate, Fr Pat Ward, and the broadcaster Fr Brian D'Arcy are officiating at the wedding.

Home bird

O'Donnell may have made millions from record sales and concerts in Ireland, the UK, America and Australia, but he remains down to earth.

When not touring, he can be found playing whist with local women in the church hall on Tuesdays. He even helps make the tea.

His last night of bachelorhood was spent at his mother Julia's house in Kincasslagh, while his bride left from the cliff-top home she will share with O'Donnell on nearby Cruit Island.

The next door neighbour drove her to church in a classic silver Rolls Royce.

Speaking before the wedding, Majella told the BBC: "I see Daniel as Daniel the person, as opposed to Daniel the entertainer, although obviously that is huge part of his life and I enjoy very much what he does and he enjoys it so much."

They are being married at the church in Kincasslagh

O'Donnell and divorcee Majella McLennan met in Tenerife two years ago.

At one point it was thought they might marry in a civil ceremony on the island, but Ms McLennan's annulment has granted them "a dream wedding".

The couple will have a working honeymoon.

They depart for the United States on Wednesday where O'Donnell will begin a tour soon afterwards.
