Harry Styles had the performance of a lifetime this past weekend -- playing Best Man at his mum's second wedding! The 19-year-old One Direction singer walked mother Anne Cox down the aisle as she married longtime partner Robin Twist, who helped raise Styles after his parents divorce (when he was just seven years old). The nuptials took place at Pecks Restaurant in Chesire, England.
