Prince George and Princess Charlotte were spotted laughing at the Queen's admission that she keeps an emergency stash of marmalade sandwiches in her handbag.
The royal siblings were clearly delighted at the revelation, which the Monarch made during a surprise comic appearance with Paddington Bear.
The monarch and the famous bear met for a chaotic cream tea at Buckingham Palace in a special, secretly-pre-recorded sequence played at the start of the televised BBC's Platinum Party at the Palace.
