The 1D singer spends the day with his family in Ireland

Niall Horan looked hot in a dapper suit for his role as best man at his brother Greg‘s wedding yesterday.

The One Direction singer wore a black waistcoat and jacket with a pink striped tie and styled his hair into its signature huge quiffed ‘do for the nuptials.

Niall, 19, drove himself and Greg, 25, to St Michael’s Church in County Westmeath, Ireland in his Range Rover and looked jubilant as he stuck his hand out of the window to wave at waiting 1D fans.

After the ceremony, Niall went over to the Directioners to sign autographs and give them hugs.

Around 150 people turned up to the church to see Greg wed bride Denise Kelly, who looked lovely in an ivory strapless dress with a long white veil.

Niall was thrilled when Greg made the surprise announcement that he and his new bride are expecting their first child.

‘It’s Niall‘s first niece or nephew,’ Greg tells The Sun.

‘So he’s delighted.’
