Queen Elizabeth II, the Duchess of Cambridge and the Duchess of Cornwall went out for tea together at London's posh Fortnum & Mason store.
The event was a rare joint appearance by the Queen and the former Kate Middleton along with Camilla, the wife of Prince Charles.
The trio met military personnel at the landmark store and toured its famous food hall, long favoured for its teas, wines and delicacies.
They were presented with luxury hampers containing delicacies including champagne truffles and dog biscuits. The Queen is a noted corgi-lover, and Kate and Prince William have a black cocker spaniel puppy named Lupo.
The store's renovated restaurant has been renamed The Diamond Jubilee Tea Station to mark the Queen's 60 years on the throne.
The royals also stopped for tea with some of the store's staff, suppliers and former employees.
