The Queen was in buoyant mood after Prince George's christening, telling guests at a Buckingham Palace reception how much she had enjoyed the event.
She greeted the Bishop of London The Right Reverend Richard Chartres - who had been at the St James's Palace service earlier today - with a warm smile.
The Queen, wearing a metallic blue and taupe dress with matching jacket by Angela Kelly, gave a gesture of mock surprise as she told him: "I haven't seen you for such a long time."
Discussing the christening, she added: "It was very nice though, wasn't it?"
The Bishop also spoke to the Duke of Edinburgh about George's behaviour during his special day, commenting: "Ah, he behaved!"
He was one of the guests at the reception for The Queen Elizabeth Diamond Jubilee Trust, of which he is patron.
Others in attendance included former Prime Minister Sir John Major, who is chairman of the board of trustees, and Secretary of State for International Development Justine Greening.
