It's set to be a special year for the Queen, who will officially mark the 70th year of her reign on 6 February. Celebrations are planned throughout the year, including one which falls on her great-granddaughter Lilibet's first birthday.
The star-studded Platinum Party at Buckingham Palace will take place on Saturday 4 June. Performers are yet to be named but it is being billed as an event that will bring together some of the world's biggest names in entertainment.
The Duke and Duchess of Sussex will also celebrate their daughter's milestone on the same day. Lilibet Diana Mountbatten-Windsor was born on 4 June 2021 at Santa Barbara Cottage Hospital, with her name chosen in honour of the Queen's childhood nickname.
