Harry Styles was best man Saturday at his mother's wedding, and his sister, Gemma, was the maid of honor.

The 19-year-old's mother, Anne Cox, wed partner of 12 years, Robin Twist, at Pecks restaurant. Twist helped to raise Styles from age 7, when his parents split.
Like mother like son, the singer wore a white rose on the label of his black suit to match the bouquet of the blushing bride.

"Harry couldn't stop smiling," one guest told Britain's Sunday Mirror. "He hardly left his mum's side and she looked really proud of him. He sipped champagne and chatted to everyone."
The reportedly low key ceremony was attended by smiling guests of the bride and groom. Styles' sister, Gemma, 20, also participated in the happy occasion as maid of honor. Styles captured them eating cake and drinking champagne in a 6-second video on his Vine account.
