Reason Prince George wears matching clothes with dad William as they break tradition watching Aston Villa

Prince George and Prince William took a break from royal duties last night as they watched their beloved Aston Villa take on Barcelona at the Nou Camp.

But the father-and-son duo also took a break from their own tradition, as George was spotted wearing a football jacket, rather than the usual suit we see him wear out and about.

Even since George started out at Eton earlier this year, the pair can usually be spotted wearing the same attire, whether it's on royal occasions or at sporting events such as Wimbledon.

But on a rainy night in Spain, where Aston Villa lost out to the brilliance of Lamine Yamal and Raphinha, the teenager was actually donning a Villa-themed jacket while his father wore a coat and cap, perhaps to avoid too much attention.

His son might also have simply been cold on a uncharacteristically unpleasant night in Barcelona, with no goals to even warm him up, but you might be wondering why the two of them are usually seen in the same suits or similar clothing, and there's supposedly a very wholesome reason for it.

According to Woman and Home, the reason George wears suits to sporting events is because his dad is his 'absolute hero' and he wants to be as much like him as possible.

Well, now that he's 13, the prince might well prefer to start wearing some of his own clothes, whether it's a Villa top with John McGinn on the back or a classic music t-shirt depicting Mozart or whoever else is popular among the Eton boys these days.

It's also nice to see the two still spending time together, especially with something that they clearly both enjoy, as there's another old royal tradition which means they technically can't travel together due to a special security measure.

King Charles's former pilot, Graham Laurie previously recalled to OK! Magazine: "We flew all four: the Prince, the Princess, Prince William and Prince Harry, up until Prince William was 12 years old.

"After that, he had to have a separate aircraft and we could only fly all four together when they were young with the written permission of Her Majesty.

"When William became 12, he would fly normally in a 125 from Northolt and we would fly the 146 out with the other three on."

Since both of them are future kings, it's important that they're kept safe at all times but clearly sometimes the football is too important, because who'd have thought that Aston Villa would be playing Barcelona in the Champions League just a few years ago.
