A cheeky young boy stopped Camilla to deliver a hilarious comment when she visited his nursery on Thursday.
Oscar Imerwood, three, is one of many children at Barnado’s Charity at Bow Day Nursery in East London.
The Queen Consort gave out Paddington bear toys which mourners left at the Long Walk in Windsor and outside Buckingham Palace following the death of Queen Elizabeth II.
During her time, Camilla also had marmalade sandwiches with the kids and was joined by Paddington film cast members Hugh Bonneville and Madeleine Harris, as well as author Michael Bond’s daughter Karen Jankel.
During the Queen Consort's visit, she gave little Noa Nkemadirim and spent time with a group of children at a table.
She then chatted with a circle of older children who were playing with blue foam, and asked them: “What are we doing here? Making a mess. We love a bit of mess.”
While the 40 children tucked into their marmalade sandwiches, Oscar declared: "I don’t like marmalade!”
When handing out the teddies, Camilla also told the children to put the tiny boots on their Paddington bears “otherwise he won’t be able to go outside”.
Hugh Bonneville, who plays Mr Brown in the Paddington films, also read Bond’s story “Paddington Takes a Bath” to the children.
As she stood to depart, Camilla told the children and their carers: “It has been a pleasure to find a home for these bears, please look after them carefully.”
Camilla had travelled to the nursery in a car filled with some of the Paddingtons, on a journey from Clarence House in Westminster, along the Mall and past London landmarks including Trafalgar Square and Tower Bridge.
The visit came after Camilla was pictured surrounded by teddies in a photo taken on October 13 to mark the 64th anniversary of the publication of the first Paddington Bear book.
The Queen's Platinum Jubilee sketch in the summer saw the Peruvian bear visit Buckingham Palace for afternoon tea, during which the Queen produced a marmalade sandwich from her handbag.
It prompted mourners to leave teddy bears and even some marmalade sandwiches among the floral tributes which amassed outside royal residences after her death.
In 2016, the Queen passed the patronage of Barnardo's to Camilla, who was then the Duchess of Cornwall.
