Princess Kate Middleton made her first public appearance since her uncle-in-law Andrew Mountbatten-Windsor was arrested for alleged misconduct. Kate, 44, stepped out at the Guinness Six Nations rugby match between England and Ireland at London's Allianz Stadium on Saturday, February 21. The Princess of Wales, the patron of English rugby, sported a royal blue peacoat with a team scarf for the occasion. "Congratulations Ireland ☘️," Kate wrote via Instagram after the game, which the Irish team ultimately won 42-21.
