The 'One Thing' star's sibling is hoping the boy band singer will be able to take the honour on his special day.
One Direction singer Niall Horan's brother has revealed how he wants the star to be his best man at his upcoming wedding.
The 'Live While We're Young' star is currently on a busy promotional campaign for the group's second studio album 'Take Me Home' and has an upcoming world tour occupying much of his 2013.
Speaking to the Irish Herald, Niall's brother Greg explained how much it would mean to have the 'Gotta Be You' star by his side.
"I really want Niall to be there on the day as my best man. Hopefully he'll be able to do it what with work and all," he confessed. "We want to work with Niall's schedule -- he's my only brother so I want him to be my best man."
He also revealed that he is proud of his brother's accomplishments with the group and that he had no fear about Niall finding love himself.
He continued: "I don't know if he'll meet someone tomorrow or in 20 years time - who knows. Whatever happens, I'll be happy for him and proud of him."
It has been rumoured this week that the former X Factor star is currently dating 20 year-old drama student Amy Green.
He has also long been linked with X Factor USA judge Demi Lovato despite insisting their pair are simply friends.
Meanwhile, One Direction have today (29th October) unveiled their new single 'Little Things', which will feature on their upcoming new album 'Take Me Home'.
