The Duchess of Cornwall has complimented a group of students dressed as knights on horseback.
Camilla told the first year musical theatre students: "You all look very smart," when she met them at a horse show at London's Olympia.
"I like your horses, they look very difficult to ride," she said.
The six men, from the Arts Educational School in Chiswick, west London, all had wooden horses attached to their imitation chainmail knight's armour.
Brad Veitch, 19, was one of the students who posed with the Duchess in front of a Christmas tree.
"It was quite inspiring," he said. "When you see royalty it gives you butterflies."
Jacade Simpson, 20, said: "It was exciting, I have never met anyone in the royal family before."
The students were performing part of the West End musical Monty Python's Spamalot for the Duchess, who is a patron of the British Equestrian Federation, in the finale of Thursday's event.
It is the seventh year Camilla has attended the London International Horse Show.
