Prince Harry performed a display of "cocky bravado" as he arrived for King Charles' Coronation today, according to a body language expert.
And the estranged Prince used his appearance to signal to the world he was "happy to be back", after months of attacks on the Royal Family from his new home in the US.
Body language expert Judi James told The Mirror that viewers of the historic event witnessed "an incredible return of the joker prince" as a grinning Harry arrived with royal cousins Princess Beatrice and Princess Eugenie.
He appeared to mimic royal cousin Eugenie's heavily-pregnant state, upon his arrival at Westminster Abbey, making her and husband Jack Brooksbank laugh.
And a confident Harry made his way up the aisle using his body language to convey an upbeat, happy approach.

Judi told The Mirror: "Harry arrived with the Sussex posse, the royal cousins Beatrice and Eugenie and their husbands, who have remained friends throughout the royal rifts.
"Chatting first to Edo he then got the attention of Eugenie and Jack and we saw an incredible return of the joker prince as Harry grinned and used two hands cupped widely under his stomach to do what looked like a mime of Eugenie’s heavily-pregnant state.
"After making the couple laugh, Harry fell back to walk in alone.
"Still smiling and with his cheeks rounded, he then proceeded to perform a display of what looked like rather cocky bravado.
"His striding walk looked jaunty as he pushed one side of his jacket away before making his way up the aisle nodding, grinning, using eye-brow flash rituals and chatting with people in the congregation as though signaling to the world that he was upbeat, confident and happy to be back."
Harry turned up at Westminster Abbey this morning alone without wife Meghan Markle, who has stayed behind in the US with their children Prince Archie and Princess Lilibet.
He was seen walking behind Princess Eugenie and her husband Jack Brooksbank, but in front of Princess Beatrice and her partner Edoardo Mapelli Mozzi.
It is the first time Harry has been in a public setting with his royal relatives since he criticised many of them in his memoir, Spare, which was published in January.
But Harry was said to have been determined to attend, with insiders saying he was cutely aware that the historic occasion will be "pretty much the most important day" of the King's life.
Judi also told The Mirror that King Charles displayed a subtle 'cut-off' gesture as he travelled past well-wishers on his way to Westminster Abbey.
She told how the pair looked slightly tense as they took their ride to the historic occasion.
She said: "Sitting almost squashed together in the small coach, with the proximity creating some sense of reassurance, Charles and Camilla’s body language here looked sweetly apprehensive and friendly, rather than regal. There were at least four signs of ongoing tension.
"Charles’s wave was a world away from the formal and rather haughty version his mother used at her coronation. His was brief and involved a waggling of the hand, to suggest lower status.
"When Charles dropped his hand from the wave he also dropped his head and at least once he looked down to inspect the palm of his hand. This would have provided a cut-off gesture, suggesting anxiety.
"When his hands clasped there was a gentle, self-comfort thumb-rub gesture. Camilla’s self-touches. Her hand rose to check her hair and her earrings at one point
"Their smiles were also tense, with tight-looking lips."
