After cheering England to victory against Wales in the Six Nations, the Princess of Wales seemed keen to congratulate her team.
Kate, who is patron of the English RFU, visited the players in their dressing room at the Principality Stadium in Cardiff for a quick chat and she even posed for some photos.
And her and Prince William's official Instagram account shared some behind-the-scenes snaps of Kate in the dressing room - delighting royal and rugby fans alike.
But eagle-eyed fans have spotted a surprise item in one of the snaps - and it has left them baffled.
In one shot, Kate can be seen posing with star player Maro Itoje while a teammate of his takes a photo of the pair.

But rather than taking the snap on a regular phone, it appears the image is being taken on a disposable camera.
One puzzled fan asked: "Is that a disposable camera in picture 2?!"
While another said: "I spotted it too! Brings back some memories."
And one fan also came up with a theory as to why a disposable camera might have been used.

They said: "Probably not allowed mobiles in private meetings for security reasons."
Later, Maro took to his own social media accounts to post the snaps of Kate taken on the disposable camera.
One of the pictures appears to be overexposed and he joked in the caption: "The old camera flash strikes again."
Meanwhile, Kate wasn't the only one who went to the dressing rooms, William, patron of Welsh rugby, also paid a visit to the Welsh players to commiserate with them.
The couple spoke of their children Prince George, nine, Princess Charlotte, seven and Prince Louis, four, during their visit.
Before the match, the couple met injured players supported by the Welsh Rugby Charitable Trust, of which William is also patron.
Kate was told that William had not yet become a father when he first met some of the injured players.

She asked how he was and laughed when she was told William had less lines around his eyes compared to now.
The pair told how George is now learning to tackle rather than playing the non-contact game tag rugby.
"They are trying to teach him the rules," Kate said.
"They move them around for their confidence. Because he is tall, he has the physique.
"But then there is Louis coming. Charlotte also does rugby."
