In June George and his family joined the Queen and other royals on Buckingham Palace's balcony as the monarch's official birthday celebrations drew to a close with the traditional fly-past of aircraft.
Royal fans are certainly in for a treat as the special Prince and Patron exhibition, which marks the 70th birthday of His Royal Highness The Prince of Wales this year, features over 100 pieces personally selected by Prince Charles himself.
"It is said to have been worn by the Emperor during his Egyptian campaign and was taken from his carriage after the Battle of Waterloo 15 years later".
A royal insider told The Sun, 'They both agreed there was little they could do but they are very, very annoyed.
And to give it even more of a personal touch, non of the pieces have explanatory text next to them to create more of visual display rather than a museum feel.
"It is meant to give a flavor of the Prince of Wales's owning residences and reflect his personal involvement", she told People.
Prince Philip is in fact "in fine form", according to the anonymous source, who added that the Queen would not have gone to Scotland if he was ill.
In the audio commentary, Charles says: "I am very fond of the two preparatory oil sketches of my sons which I acquired from the artist, Nicky Philipps, in 2009".
Among the many interesting artefacts in the exhibition include Islamic-inspired artwork and other Middle East traditions, including a moving triple portrait of three Yazidi women painted in Iraq by Hannah Rose Thomas, after they had escaped Isis captivity.
Buckingham Palace's switchboard is said to have been inundated with calls over the rumours.
