King Charles, Prince Louis melt hearts with sweet balcony moment

Prince Louis is a charmer for sure. 

Prince William and Princess Kate's younger son Louis who often brings smile to royal fans once again drew attention for the right yet cute reason at this year's Trooping the Colour parade.

The seven-year-old was seen copying his grandfather King Charles' wave during the balcony appearance at Buckingham Palace. 

The young royal was seen glancing towards the King for cues before imitating his graceful to the cheering crowd below. As the Royal Family paused briefly during their traditional balcony moment, King Charles resumed waving-catching Louis' attention in the process. 

Noticing his grandfather's move, Louis quickly followed suit, playfully mimicking the royal wave as other family members smiled and joined in on the fun. 

The lively Prince kept enthusiastically waving to the crowd even after several royals had begun making their way back inside. 

In a lighthearted moment, Louis managed to sneak in one final wave just before his mother gently guided him out of sight. Earlier in the day, Louis also shared an endearing moment with his eldest brother, Prince George, during their carriage procession along the Mall.

As their courage journeyed towards Horse Guards Parade, a keen-eyed lip reader caught a sweet moment between the two royals.

Louis was seen turning to his brother to ask: 'Should I wave?' 'It's up to you,' George was observed responding, the lip reader told The Sun. 

Noticing the beautiful weather, George also remarked, 'I can't believe how sunny it is.'

Encouraged by his older brother, Louis then said: Let's do it together.'
