The Waleses shared the tidbit at a rugby match between England and Wales in Cardiff on Saturday—where they found themselves cheering for opposing teams. William, as Patron of the Welsh Rugby Union, naturally threw his support behind the Welsh side, while Kate, Patron of the Rugby Football Union, cheered on England.

The 43-year-old looked tense as she whispered a comment to Rob Udwin, president of the RFU, who was sat next to her for the game. Speaking to The Mirror, a lip reader confirmed that the Princess looked nervous ahead of the match, despite England taking the win without too much trouble.

Kate Middleton and Prince William are ringing in the weekend at the Wales vs. England Six Nations Match. All about their royal rugby rivalry and today's game.

As one might have guessed from his title as the prince of Wales, William is the patron of the Welsh Rugby Union, and therefore headed into Principality Stadium in Cardiff, Wales with a single goal: to cheer the Dragons on to victory.
