She has not long abdicated the throne to heir apparent Olivia Colman.
But it appears Claire Foy's reign may long continue – after she was spotted filming for the next series of The Crown.
Wearing a white dress and pearl necklace, the 35-year-old was seen recreating the Queen's 21st birthday speech in what is thought to be a 'flashback' scene to feature in the fourth series of the hit show.
In the iconic radio broadcast, recorded during a tour of South Africa in 1947, the young Princess Elizabeth dedicates her life to the service of the Commonwealth.
Foy, who has just finished a run at the Old Vic starring alongside former co-star Matt Smith, was replaced by Colman, 45, ahead of the latest series to reflect the ageing of the monarch.
