Niall Horan is celebrating his 29th birthday today but has also paid tribute to the late Queen Elizabeth II.
He has spoken about how anxious he was before meeting the Queen. He was just 20 at the time and was with the band One Direction. The Mullingar singer says it was the most daunting moments of his career.
Although he'd met many of the Royals before, meeting the Queen made him the most nervous he has ever been.
