One Direction heartthrob Harry Styles could not stop smiling as the best man at his mother's wedding.
Styles' mother Anne Cox married Robin Twist on June 1 and the singer barely left his mother's side at the ceremony in Cheshire, England, reported Contactmusic.
"Harry couldn't stop smiling. He hardly left his mum's side and she looked really proud of him. He sipped champagne and talked to everyone," a guest said.
The 19-year-old pop superstar and Twist wore matching black lounge suits, while Cox was seen in an ivory, floor-length silk dress.
The ceremony - held for 42 family and friends - was kept a secret with guests only told at the last minute.
"They chose the medium-priced wedding package. It was a lovely day," an insider revealed.
Styles was joined by second best man Mike - Twist's son from a previous relationship - while his sister Gemma, 20, was maid of honour.
