The theatre actor, 21, has been seen after filming for series six of the Netflix smash-hit.
Ed was all smiles as he left the set in a car holding a bag and flowers.
The next series, expected to be released next year, will include Princess Diana’s tragic death.
In the previous series, the real life son of actor Dominic West, who is playing Prince Charles in The Crown, played Prince William.
Born in 2004 Senan West was picked after a nationwide search for a suitable youngster to play the royal.
The young actor portrayed the Prince as he grows from a boy to a man.
Senan is one of four children the actor has with his wife Catherine Fitzgerald.
William’s mother, Diana, previously played by Emma Corrin, is now played by Elizabeth Debicki.
Meanwhile his grandmother, the Queen, is portrayed by Imelda Staunton, who took over the central role from Olivia Colman.
