ONE DIRECTION star Niall Horan tried to stay in the background as much as possible as his big brother said "I do".
The wedding of Niall's elder sibling Greg and bride Denise Kelly took place in the village of Castletown Geoghegan outside Mullingar, Co Westmeath, yesterday.
It drew a crowd of up to 100 teenage fans who were hoping to catch a glimpse of the boyband singer on a rare visit back to Ireland.
And there was pandemonium when Niall (19) pulled into the car park at St Michael's Church.
He chauffeured his 26-year-old brother and father Bobby – all dressed in grey suits with pink and white striped ties – in his black Range Rover to the ceremony.
The singer signed a few autographs when he arrived and greeted fans as he left, but was insistent that the day remain about Greg and Denise.
Three security guards were on standby to ensure no uninvited guests gained access to the chapel. There was only one moment of worry when a 19-year-old woman managed to climb into Niall's unattended 4x4 before the service kicked off.
Everything else went without a hitch, with the bride arriving fashionably late, at 1.30pm.
She was accompanied by her father Liam Kelly and wore a strapless, champagne-coloured dress with ruche detail that was bought locally.
Denise wore her hair swept back off her face and had a veil embroidered with pearls, while her two bridesmaids were in cerise pink and royal blue.
The church was decorated in boho chic style, with Leitrim-based florist La Belle Fleur providing the "forest-inspired" floral arrangements.
Dressed in a matching purple dress and hat, proud mother Maura Gallagher said she couldn't be happier to see her first child walk down the aisle.
"The wedding was a bit emotional for me," she said.
"All I was doing was staring at Greg. He doesn't mind being upstaged at all – he's so proud of Niall. It's nice for Greg to have a bit of a fuss for a change."
Meanwhile, local pub owner Paul Claffey told the Irish Independent that whenever Niall returns to his hometown it becomes "circus-like".
"It's always madness when Niall's around, but he's a great lad and they're a lovely family. A niece of mine actually came up from Dublin to see him. He's a huge attraction, but we're all very supportive and delighted for him – and of course the couple too."
The newlyweds and their 150 guests enjoyed a reception at Lough Rynn Castle in Co Leitrim, the same place that rugby player Brian O'Driscoll and Amy Huberman held their wedding in July 2010.
It was very much a family occasion for the Horans in the build-up to Greg and Denise's big day, despite the cameras filming Niall for the forthcoming One Direction 3D movie.
The groom and best man had spent the night before in local pub Danny Byrne's to watch the Ireland match.
The pop star was also spotted collecting a guitar from a Mullingar store, which he brought with him to the reception.
