Kate Middleton “appears tense” when she watches rugby match with Prince William

The Prince and the Princess of Wales were discovered in the Principality Stadium when they saw how England scored the Six Nations against Wales in the rugby match.

The royal couple, who acts as a customer of their respective rugby unions, expanded their support for opposing teams during the game. However, Kate seemed to be quite “tense” on the picture shared on the media.

In addition, Kate's presence on the game meant that she probably missed a special family procedure for Grace Matthew's four -time birthday.

Please note that Grace is the daughter of Pippa Middleton and James Matthews, who today celebrated their milestone with their other siblings Arthur and Rose in Berkshire.

Prince William, as the patronage of the Welsh rugby Union, cheered Wales, while Princess Kate supported the beach in her role as patron of Rugby Football Union and Rugby Football League.

While Kate may have missed Grace's birthday celebrations, the princess will probably find a special way to mark the occasion with her niece for a later day.
