The Princess of Wales demonstrated once more that she is the queen of love and affection during a wonderful moment during her annual Christmas carol session.
Kate was pictured kissing the Duchess of Edinburgh as she welcomed her to Westminster Abbey for the festive Together at Christmas event on December 6.
The royal bash, which was attended by senior royals as well as community heroes and charity officials, included an evening of music, introspection, and winter happiness.
She turned attention in a gorgeous red longline coat designed by Sarah Burton for Alexander McQueen, and went in for a sisterly kiss on Sophie's cheek.
Sophie, who looked lovely in a long purple paisley-patterned dress paired with a clean white jacket, couldn't stop smiling as the two enjoyed this heartwarming moment.
Ingrid Seward, author of My Mother & I: The Inside Story of the King and Our Late Queen, recently spoke with HELLO! about their relationship, stating, "They have a sisterly bond, and Sophie is like the older sister Kate never had."
Both recognized for their warmth and loving attitude, the couple is passionately protective of their families.
Sophie, who has raised her own small family, understands Kate's struggles in combining motherhood and the royal limelight.
