Prince Harry watched on as the crown was placed on his father King Charles III's head at the Coronation.
During the live footage of the historic event, the Duke of Sussex was seen watching on as the archbishop raised St Edward's Crown above his father's head before crowning him, writes The Mirror.
The congregation then paid homage to the new monarch, and Harry was seen, along with the other royals around him, speaking the words: "God save King Charles. Long live King Charles. May the King live forever."
The Duke of Sussex arrived in the UK just yesterday but is due to fly back to his home in California shortly after the ceremony as today also marks his son, Archie's fourth birthday.
Harry was then spotted joking with Princess Eugenie's husband about his quick visit to the UK, in which he plans to be here for less than 24 hours.
According to a lip reader, Harry joked about his busy day and told Jack he would be leaving at "about quarter to four", to which Jack Brooksbank replied: "Oh really, when?"
An expert has also claimed Harry made an awkward "ignore" gesture as he got his first glimpse of Prince William.
King Charles III was reportedly "delighted" that Harry decided to attend the historic ceremony, amid reports the two have made moves to clear the air since their public falling out.
