U2 star Adam Clayton has finally found what he was looking for after marrying Brazilian girlfriend, Mariana de Carvalho.

The 53-year-old bassist finally left the bachelor lifestyle behind after exchanging vows with the South American model in a low-key 15-minute ceremony at a Dublin registry office on Wednesday morning.

The smitten pair were joined by just 18 of their closest friends and family, including bandmate The Edge and his girlfriend Morleigh Steinberg.

The Edge, in his trademark beanie hat, even acted as the official photographer for the happy couple.

A relaxed-looking Clayton wore a dark navy suit and purple spotted tie, while his young bride - whom he proposed to in Carnival in Brazil earlier this year - looked stunning in an elegant knee-length Chloe dress.

Following the wedding, friends and family joined the media-shy couple, who have been dating for four years, for a knees-up at Clayton's plush home in Rathfarnham, Dublin.

Five people carriers escorted the guests to the reception, including the new bride's mother, who flew in for the celebrations from her home in Brazil.

U2 manager Paul McGuinness and drummer Larry Mullen arrived later to join in the celebrations, although singer Bono was unable to attend.

The pair are now understood to be preparing to entertain up to 150 guests at an upcoming  three-day wedding party at a top-secret location in the South of France.

It is rumoured that the festivities will take place at the luxurious Eze Les Roses villa outside Nice, which is owned jointly by Bono and The Edge.

A spokeswoman for the rocker confirmed the nuptials had taken place yesterday (Wed), adding: "Adam is delighted to confirm that he married Mariana de Carvalho today in Dublin."
Clayton, who has been previously engaged twice, had never married before.

He was famously engaged to supermodel Naomi Campbell for a few months in 1994, but their relationship ended the same year.

Then in 2006 the bassist proposed to Susie Smith, a former assistant to the band's manager, Paul McGuinness.  However, the relationship ended three years later.
