RONAN and Yvonne Keating put their marital woes behind them to celebrate the big day of close pals Cecelia Ahern and David Keoghan.
The estranged couple reunited yesterday after the Boyzone star jetted home for what he thought was the Christening of their good friends' first child.
Cecelia and her long-time fiance (both 28) fooled dozens of pals by holding a secret wedding in north Dublin followed by a glitzy reception party at the Lyons Estate in Kildare.
But many eyes were on the Keatings who were back together in public for the first time since announcing their separation almost a month ago.
Guests said that the pair attended the party as a couple but were careful not to steal the limelight from Cecelia and David.
It is the first function the Keatings have attended together since the shock news.
The four are mutual friends and were in close contact during the turbulent days after the statement announcing Ronan and Yvonne's separation.
Cecelia was among the first to visit Yvonne at her home in Abington estate, while Ronan is understood to have had a heart-to-heart with David.
Former Taoiseach Bertie Ahern walked his millionaire daughter Cecelia down the aisle at St Nicholas of Myra Church in Kinsealy.
The guests had been invited to the Christening of Robyn Keoghan but quickly discovered that the six-month-old's baptism had actually taken place earlier in the week.
Afterwards, the wedding party headed to the exclusive Lyons Estate in Celbridge where all the stops were pulled out to ensure it was a night to remember. A source close to the Aherns said the young couple were determined that it would be "a very intimate affair", which is why they told no one about their plans.
"They are very private individuals and they wanted it to just be family and close friends which is why they decided to do it this way," she said.
Security was tight at the gates to the Kildare venue, with a team of door staff bearing clipboards only letting in guests whose names had been pre-approved.
Attendees enjoyed a champagne reception followed by a four-course sit-down dinner alongside Cecelia's mum Miriam and her partner Terry McCoy.
Also there was the writer's proud sister Georgina and her Westlife partner Nicky Byrne alongside all of David's immediate family. The Keatings are said to have enjoyed the day, although friends are still not overly hopeful that they will mend their broken marriage.
One guest told the Herald: "It was a total surprise to all of us. The invitation was for Robyn's Christening so we were really surprised when we got there to find out it was for a wedding.
"It was an amazing day and they are such a special couple, it was a real honour to witness their happy day."
Cecelia and her athlete-turned-actor partner have been dating for more than six years and welcomed their first baby last December.
One of Ireland's most successful chick-lit authors, the petite blonde only recently said that she didn't feel any pressure to get married.
But she did say that whenever they do walk down the aisle, it would be to be a private affair.
"David and I made a commitment to one another a long time ago, which is as strong to me as marriage. If and when marriage happens, it will be a decision David and make in our own time, on our own terms," she said.
