Prince George’s adorable big brother moment with Prince Louis has left royal fans in a frenzy.

The Royal Family gathered on the Buckingham Palace balcony for Trooping the Colour, a celebration for the King’s official birthday on Saturday.

Ten-year-old George was seen gently guiding his younger brother Louis amidst the grandeur of the occasion.

Cameras caught the sweet interaction which showcased their close bond, with the clip going viral on social media.

Prince George can be seen telling his younger brother to face the public when Louis had turned to speak to his father, Prince William.

Princess Charlotte was also keeping an eye on the five-year-old, reminding him of the proper way to behave rather than dancing and pointing.

In one clip, the princess can be seen telling Prince Louis to put his arms down as the fanfare begins for the national anthem.

Trooping the Colour also marked their mother, Princess of Wales’ first public appearance this year, following her cancer diagnosis.

There was also a funny interaction between Princess Kate and her youngest son while they and her other two children were in the carriage during the parade.

Lip reader Nicola Hickling spoke to the Mirror and claimed that Louis asked: “Can I play with the beads?” to which the princess firmly replied: “No. I need you to concentrate on the parade.”

At one point Princess Charlotte said to him: “You have to stop doing that. Watch the parade”, to which he replied: “I won’t”. Charlotte added: “Do as you’re told” but her brother responded: “Nope”.
