Prince Louis made his official royal balcony debut yesterday, and just LOOK at him

What a cutie!

Yesterday, a number of members of the Royal Family stepped out onto the balcony of Buckingham Palace.

The reason was The Trooping of the Colours, the event that formally kicks off the Queen's birthday celebrations.

It was quite the day, with so many familiar faces making an appearance.

The beautiful Meghan Markle was there, marking her first official appearance since the birth of her son.

Princess Eugenie and Princess Beatrice were also there, along with their father.

And of course, The Cambridges were on the balcony, looking like a gorgeous little family.

But if we're being honest, we watched the event for one reason, and one reason only - Prince Louis.

The Trooping of the Colour was the Prince's royal balcony debut, and lads, it didn't disappoint.

First of all, we need to discuss his outfit, which was just perfect in every way.

Prince Louis wore his uncle Harry's hand-me-downs, wearing the same outfit that Harry wore to The Trooping of the Colour in 1986.

How sweet is that?

Then, outfit aside, there was Prince Louis' general banter - and his hilarious facial expressions.

The one-year-old royal waved at the crowds, almost knocking of Camilla's hat at one stage.

Louis was expected to make his debut at Trooping this year, judging by his age.

The prince is almost 15 months old; Princess Charlotte was 13 months old when she attended her first Trooping in 2016.

Prince George, however, was nearly two years old when he made his debut. The future King was considered too young to attend back in June 2014 when he was just ten months old.

Fair enough.
