Prince William's private office was on show in his very first Instagram Q&A yesterday.
And eagle-eyed followers of the royals spotted a heartwarming tribute to his other half, Catherine, Duchess of Cambridge in the background, according to The Mirror.
Speaking on a live stream on the popular social networking platform, Wills took questions on a range of topics, such as climate change, speaking foreign languages, and even whether he believed that unicorns are real.
On the sideboard behind him viewers noticed a 'beautiful' portrait of himself and Kate Middleton, which dated from the celebrations surrounding their engagement.
The pair look youthful in the picture taken in 2010 by Mario Testino, a Peruvian photographer who had previously worked with Diana, Princess of Wales.
Mr Testino said at the time: "They are in their prime and brimming with happiness. I have never felt so much joy as when I see them together."
Another family photo could also be observed to the right of William's office, on a different sideboard.
This was a picture taken of his two eldest children, Prince George and Princess Charlotte, who can be seen in their adorable school uniforms.
The online event was held in aid of the very first Earthshot Prize awards, which are being held on Sunday.
This £50,000,000 scheme was set up by the Prince and BBC legend David Breakthrough to champion innovation in the fight against climate change.
The huge sum will be distributed over the next 10 years to winners in five different categories, who will win £1,0000,00 each.
The Duke said: "The next 10 years present us with one of our greatest tests - a decade of action to repair Earth" .
Sunday's ceremony will be broadcast live on BBC One and Discovery+, and will include performances from Coldplay, Ed Sheeran, Shawn Mendes and KSI. The Duchess of Cambridge and Emma Watson will be just some of the stars to present awards to the winners.
