Harry Styles was best man at his mum's wedding over the weekend.
The One Direction star stepped up to the important role at mum Anne Cox's wedding to Robin Twist, says the Daily Mirror.
Anne and Robin have been together for 12 years, and he helped to raise Harry after his parents split when he was seven.
Harry's sister Gemma, 20, was maid of honour and Robin's son Mike from a previous relationship was also best man.
The nuptials took place at Pecks restaurant near Congleton, Cheshire with the location kept a secret from guests until the last minute so that the day wasn't deluged with One Direction fans.
A guest told the Mirror: "Harry couldn't stop smiling. He hardly left his mum's side and she looked really proud of him. He sipped champagne and chatted to everyone."
According to The Sun, it's thought Harry, 19, sang a few songs at a later party in a nearby golf club.
