He is small, but he is mighty. He is young, but wields power. He is Prince Louis and he has gone viral, once again.
The young royal, only 5, stole the stage after the Trooping the Colour ceremony on Saturday, where his grandfather King Charles saddled up for the illustrious occasion.
Prince Louis joined other members of the royal family, including his parents, The Prince and Princess of Wales, on the famous balcony at Buckingham Palace after the festivities, and garnered massive attention for his antics, albeit a regular tradition now.
The young prince was pictured defiantly outstretching his arms, showing off two little fists, much to his parents suppressed amusement.
