It was a top-secret wedding with arrangements reminiscent of U2's 'Mysterious Ways' as the band's bass player Adam Clayton married his girlfriend in a low-key ceremony in Dublin city centre.
Adam (53) married his Brazilian model girlfriend Mariana de Carvalho at the ceremony attended by a small group of close friends and family.
He had proposed to Mariana at the Carnival in Brazil earlier this year following a four-year romance.
Yesterday's ceremony, which was attended by U2 guitarist The Edge and his wife Morleigh Steinberg, took place in a registry office in Dublin's Grand Canal Street.
Neither lead singer Bono nor drummer Larry Mullen were present at the civil ceremony but Mullen was seen arriving at a small celebration with Adam and his new bride at their plush 18th Century home in Rathfarnham later on.
The happy couple posed for pictures in the sunshine at the registry office before they were whisked away, along with Mariana's family, in a small convoy of black people carriers.
It has been rumoured that a larger reception will be held in the South of France in the coming days.
Larry Mullen arrived at the house at about half one accompanied by his partner of more than 30 years, Ann Acheson.
Asked about the wedding, the drummer quipped: "Yeah I think marriage is a great -- just not ready for it myself."
He said he had "no idea" how many people would be attending the celebration at Clayton's home but later said that Bono was going to be there along with his wife.
However, while Ali Hewson was later spotted leaving the bash, there was no sign of the usually high-profile singer.
Mullen added: "We're working in the studio so we're dropping in for lunch and then we'll go back to work, you know."
Asked if U2's bass player would be working on his wedding day, he joked: "I hope so -- we've an album to finish."
U2 are currently putting the finishing touches to their 13th studio album, which is set to be released before the end of the year.
The band's manager Paul McGuinness was seen leaving the house at about 6pm.
Larry and the Edge left about half-an-hour later, with Bono's wife Ali Hewson (pictured) driving out in another car.
They were followed shortly after by Adam driving a grey Audi with a number of other passengers, including his wife Mariana.
U2's publicist Lindsey Holmes last night refused to go into detail on yesterday's celebrations or on the rumours that a larger ceremony is planned in France.
The couple had been dating for four years and were last spotted together at the funeral of poet Seamus Heaney in Donnybrook Church.
It is not known where the couple plan to honeymoon.
Adam, originally from Malahide, was previously engaged to supermodel Naomi Campbell in 1994 but their relationship ended the same year.
More recently he was engaged to Suzie Smith, a former assistant to band manger Paul McGuinness, but they split up in 2007.
Speaking in 2009 about his single status, he said: "I've had girlfriends throughout the last 20 or 30 years. It's just that there were times when I met people that fascinated me and times I didn't."
