Prince George and Princess Charlotte have matching Aston Villa kits.
The children of Prince William and Duchess Catherine - who are expecting a third child together - have their very own sports gear by their father's favourite football team and love to wear them, according to nine-year-old Brian Mulonbi, who recently met Catherine during the couple's official trip to Coventry.
The youngster said: "Kate told me that George and Charlotte love putting on Villa kits. I told her I am an Arsenal fan, so I don't really like Villa kits."
Whilst Taylor Mosley, also nine, said: "I said to them that I'm a Villa fan, because I know William is a Villa fan. He said he wants Sam Johnson to be our goalkeeper forever."
Taylor added: "She said, 'I have to be loyal to my husband!'"
William previously revealed that before Charlotte turned two last May, she was already a "very good footballer".
Speaking at Wembley Stadium in north London to celebrate his 10 years as President of the Football Association, the Villa fan said: "She's a very good footballer. You hold her hand and she kicks it. Very sweet."
Catherine previously hinted that her favourite soccer team is Chelsea.
The Duchess bonded with one eight-year-old, named Rjay Bryan, over their support for the same club.
He explained: "We high fived because she supports Chelsea and I support Chelsea.
"I love people who support Chelsea."
William admitted he thinks it'd be "fantastic" if his son follows him in supporting Villa.
Asked whether he'll try to influence the team his son supports, he explained: "The responsible thing would be to say, to let [George] make his own mind up, but I think I might be quite biased.
"I haven't quite worked out how to play that yet. Of course he can support whoever he wants, but if he supports Villa, it'd be fantastic. I'd love to go to the odd match with him in the future.
"It'll probably end up being that [Princess] Charlotte is the Villa fan and George will go and support someone else!"
