Prince William and Princess Kate have a friendly rivalry with one another, often attempting to out-compete the other during some of their more active outings.
And Saturday will see this rivalry rear its head once again as the pair travel to Cardiff to watch England and Wales play in the Six Nations tournament. As Prince of Wales and patron of the Welsh Rugby Union, William will no doubt be backing the dragons, but as the patron of the Rugby Football Union, Kate will have her support firmly planted with the English roses.
Kate herself has been known to play a little rugby, and you can see her show off her skills in the video below...

In the past, the pair have been known to bring their children to matches, with young Prince George watching the men's Euros in 2021, and also joining his parents to an England and Wales match last year. However, on this occasion, it was just the Prince and Princess who headed out for the match.
Kensington Palace has confirmed that the Prince and Princess will meet injured players who are supported by the Welsh Rugby Charitable Trust during their trip.
They will then officially open the Sir Tasker Watkins Suite - a new space at the Stadium which is dedicated for use by the injured players and their families ahead of matches.
The pair made sure to wrap up warm for the outing, with William in a black coat and red scarf, while Kate looked so stylish in a red and white houndstooth coat. Princess Kate previously wore the outerwear garment in 2018 when she was pregnant with Prince Louis.
The mother-of-three-to-be stepped out in the luxurious piece during a visit to the Karolinska Institute in Stockholm, to hear about Sweden's approach to managing mental health challenges. The coat concealed her blossoming baby bump and was teamed with a Chanel calfskin bag and sheer tights.
Ahead of the match, the royals were on the same team as they unveiled a plaque in front of members of the Welsh Rugby Charitable Trust.
Ahead of the match, William told a group of injured players joking that they needed a "little lift" and that the atmosphere would be "tense" with his wife if England were to triumph.
This was the pair's first match since becoming the Prince and Princess of Wales, and it led to them singing the Welsh national anthem. Find out how they got on!
William will leave the match slightly disappointed, but Kate will surely be grinning all the way home, as England triumphed over Wales by 20-10.
