Perfecting his royal wave at Trouping of the Colour

With the territory of being HRH, the young prince has plenty of opportunities to perfect his royal wave. But none were more adorable than his appearance at the Trooping the Colour in June of 2015. The ceremony celebrating his great-grandmother, Queen Elizabeth II's annual birthday parade had his father, William laughing at his young tot.

According to the Daily Mail, George's nickname for his grandmother is slightly more conventional then what his father used to call the Queen, with high society gossip columnist Richard Kay saying that Prince William used to call the Queen "Gary" when he was younger after finding it difficult to pronounce "Granny."

Uncle Harry's wedding to Meghan Markle

While all eyes were on Meghan Markle during the Royal Wedding this past spring, Prince George did something he usually doesn't do: he wore pants.

Prince Harry's 4-year-old nephew, who usually only ever wears shorts, donned a miniature version of Harry's military uniform during the wedding of the year. The formal look was complete with black pants with a red stripe and a matching three-quarter length black jacket as he served as a page boy in the wedding.

The other four page boys also wore miniature versions of the Blues and Royals uniform that Harry and William donned. Each page boy had their initials embroidered in gold on their shoulder straps.

Though George has been spotted wearing pants before, the Royal Wedding was his first official engagement where his legs were completely covered. Etiquette expert William Hanson told Harper's Bazaar UK that the reason George typically wears shorts has to do with royal and aristocratic tradition.

"It's a very English thing to dress a young boy in shorts," Hanson said. "Trousers are for older boys and men, whereas shorts on young boys is one of those silent class markers that we have in England.

The prince turns 5!

In celebration of Prince George turning 5 years old on July 22, Kensington Palace released a new portrait of its young royal highness.

Hard to believe, but the oldest son of Prince William and Duchess Catherine Middleton is celebrating a major milestone this year and the Royal Family is paying tribute to its little prince with a precious portrait taken in the garden of Clarence House.

With a big, toothy grin, the photo is a sharp contrast to the bouncy confidence so many are used to with the little prince. George is seen leaning against a brick wall sporting a white polo for the occasion and as Entertainment Tonight reports the image, is shot by royal photographer, Matt Porteous shortly after younger brother, Prince Louis' christening on July 9.
