Harry Styles Is All Smiles As Best Man At His Mum Anne Cox's Wedding (PICS)

Harry Styles is all smiles after being on best man duties at his mum's wedding this weekend.

The One Direction star helped organise the top secret bash for 43-year-old Anne Cox's marriage to Robin Twist.

Anne did Harry proud in a stunning ivory floor-length silk dress, arriving at Pecks restaurant near Harry's family home in Cheshire in a Bentley.

The boybander and stepdad Robin wore matching lounge suits, while Harry's older sister Gemma, 20, was maid of honour.

The couple exchanged vows in front of 42 family and friends before partying at a nearby pub, where Harry belted out a few tunes for the wedding guests.

To avoid Anne's big day being invaded by One Direction fans, venue details were kept secret from the guests until the last minute.

Even a decoy bus filled with fake wedding guests was arranged, which was sent to Doncaster racecourse 80 miles away to put fans off the scent.

One 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.”
