The Princess of Wales supported the Great Britain Olympic team in a rare video message captured alongside her husband.

Middleton radiated beauty with her dark brown hair swept to the side as she wore a navy blue striped sweater, while William sported a blue Adidas Team GB polo shirt and a scruffy beard.
