Camilla, Duchess of Cornwall, got behind the bar of the Rover's Return, the fictional pub on "Coronation Street."
The duchess says she is a lifelong fan of the show, set in the fictional working-class community of Weatherfield.
Camilla visited the set in Manchester, northwest England and watched the cast film a scene from the long-running soap.
She said the show was "a wonderful British institution."
Thursday's royal visit marked the 50th anniversary year of "Coronation Street," which began in 1960.
Camilla says she would like to appear on the show. Her husband Charles, the heir to the British throne, had a walk-on part 10 years ago.
