The King and Queen of cute! Prince George and Princess Charlotte's best moments

Welcome to the family, Prince Louis. George and Charlotte lead the charge at their baby brother's christening.

Can we please take a moment to appreciate the gift that is Princess Charlotte, aka our new favourite royal? From her royal wave to finally getting to hear her sweet voice, the proud big sister was the shining star at Prince Louis' christening.

Gorgeous George in his trademark shorts has grown up before our eyes.

Back to the very beginning! William and Kate introduce the world to George on July 22, 2013 and almost a year and a half later, they do it all over again with Charlotte on May 2nd, 2015.

The stunning snaps were taken by Duchess Catherine in April, 2016 at Anmer Hall in Norfolk.

She's a royal ray of sunshine.

And who could forget cherubic Prince George as a baby? Here he is at his 2013 christening.

It might have been George's first official royal tour to New Zealand and Oz but the future King couldn't have looked more disenchanted about the whole affair. And that's why we love him!

Friends in high places! George stole the show yet again when he met President Obama in April 2016 rocking a bespoke dressing gown.

Look at me go! George showed off his rocking horse skills as Duchess Catherine proudly clapped him on. The toy was given to George from The Obamas when he was born.

She might not be the direct heir to the throne but when it comes to family dynamics, The Queen has confessed her great-granddaughter Princess Charlotte, two, is very much in charge.

And she especially loves to boss her four-year-old big brother Prince George around!

While Duchess Kate says her daughter is "the one in charge."

In January, the world was given a glimpse of Princess Charlotte's bubbly personality as she confidently posed on the steps of her Kensington Palace home before her first day at Willcocks Nursery School in London.

The George effect! Shortly after the Cambridges released this family photo for Mother's Day, parents flocked to buy jumpers with their little one's name emblazoned across it, just like the one George wears by designers My1stYears in the happy snap.

In 2014, the Royal Family presented the world with the cutest Christmas gift of all - this official series of snaps featuring Prince George casually hanging out in the courtyard at Kensington Palace.

In his third birthday portraits the young Prince tried to feed the family dog, Lupo, some of his ice cream! "I really enjoyed the opportunity to take these photographs of Prince George. It was a very relaxed and enjoyable atmosphere," photographer Matt Porteous explained. (Image/Matt Porteous)

The beautiful shots, which were shared on the Royal Family's official Facebook page, were taken at the Cambridge's Norfolk home in mid-July. "The Duke and Duchess hope that people will enjoy seeing these new photographs. They would like to thank everyone for all the lovely messages they have received as Prince George celebrates his third birthday," the official statement said at the time. (Image/Matt Porteous)

It was a family affair on Christmas morning in 2016.

Prince George was so well behaved, he was given a candy cane at the end of the church service.

Princess Charlotte is already speaking Spanish.

While big bro George wants to be a police officer when he grows up.

Aww, their final Christmas card as a quartet.

Last year, Prince George celebrated a huge milestone as he started school at Thomas's Battersea in London.

"She's very sweet and very confident - she's always chatting away," an insider recently told People of Princess Charlotte.

"She is so polite, but also fun and energetic."

This family couldn't be more picture-perfect if they tried.

We can't wait to see George and Charlotte interact with their new sibling.

Pippa who? The Royal rascals totally stole the show at aunt Pippa Middleton's wedding last year.

With the help of mum, the pair were pageboy and flower girl.
