Prince George's Most Adorable Moments

Kate Middleton took two sweets photos of her eldest chlld in honor of his seventh birthday. Taken in early July, she shared one photo of him grinning from ear to ear while rocking a green polo shirt, and a second of him looking just as happy while wearing a camo tee. In both, he looks more and more like his dad, Prince William, than ever before! 

Four generations of royals! George joined his father, Prince William, great-grandmother Queen Elizabeth II and grandfather Prince Charles for a new photo of the British line of succession as part of the launch of The Royal British Legion’s "Together at Christmas" initiative. The 93-year-old Queen, as well as the Prince of Wales, the Duke of Cambridge and 6-year-old George were pictured preparing special Christmas puddings in the Music Room at Buckingham Palace.

What a sweet big brother! Prince George posed with his little sister, Princess Charlotte -- who was starting her very first day of school -- as they got ready to head off to Thomas’s Battersea school with their parents, Kate Middleton and Prince William, on Sept. 5. 

Aye aye, captain! Prince George has lost his two front teeth, and the milestone was adorably on display when he attended the King's Cup Regatta in Cowes, England. The little royal was outfitted in a captain's hat, blue-and-white striped polo shirt and a black life vest as he sat amongst other members of his family. 

Happy 6th birthday, Prince George! To mark the occasion, Kensington Palace shared a trio of precocious pics of Prince William and Kate Middleton's firstborn, including two that show a couple of missing teeth in his contagious smile. "Happy Birthday Prince George! The Duke and Duchess of Cambridge are very pleased to share new photographs of Prince George to mark His Royal Highness's sixth birthday," Kensington Palace captioned the portraits, shared on July 22. "This photograph was taken recently in the garden of their home at Kensington Palace by The Duchess of Cambridge. Thank you everyone for all your lovely messages!"

The eldest of Prince Harry and Kate Middleton's three children made some confused but adorable faces as he took in the Trooping the Colour parade, which takes place yearly in honor of the queen's birthday, alongside his sister Charlotte on the Kensington Palace balcony on June 8.

Garden variety fun! George and his little sister, Charlotte, dipped their toes in a stream at the RHS Back to Nature Garden, which was co-designed by their mom.

George flashed a huge grin in his family's Christmas card photo, which was taken by photographer Matt Porteous at Anmer Hall. How sweet do all five royals look?!

He's an old pro at this! The young prince of Cambridge posed for a pic during Princess Eugenie of York's wedding to Jack Brooksbank in Windsor, England.

Happy fifth birthday, Prince George! 

During a flypast honoring the 100th anniversary of the Royal Air Force, Princess Charlotte and Prince George captured hearts around the globe -- and they weren't even at the event! While Charlotte stuck out her tongue as she and her brother watched the flypast from the balcony, George looked like he was in total awe of the whole scene.

Prince George, who is normally seen out and about in shorts, wore pants for the first time in public while serving as a pageboy for his uncle Prince Harry's royal wedding to Meghan Markle on May 19. The black pants were custom-made by Savile Row tailors Dege & Skinner and featured red stripes down the leg. He paired them with a formal black jacket similar to the Blues and Royals coat his father, Prince William, wore for the ceremony.

When it comes to Christmas cards, the royal family does it best! George and Charlotte were front and center for the annual photo shoot, shot by Getty photographer Chris Jackson, rocking light blue ensembles that matched their parents' dapper outfits.

Prince George and dad Prince William posed liked the pros they are on the younger royal's first day of school. 

Ready for takeoff! The blonde cutie pie was pretty happy about getting the opportunity to tour helicopter models before the royal family took off from Hamburg on the last day of their royal visit to Germany and Poland.

George couldn't have looked any cuter on his fourth birthday, flashing a giant smile as Getty Royal Photographer Chris Jackson snapped his pic. The birthday boy looked regal in a blue-and-white striped button-down shirt, with his hair combed to the side.

Standing alongside his sister on the balcony at Buckingham Palace, George made funny faces during the annual Trooping the Colour parade.

Happy holidays! The towheaded tyke enjoyed a candy cane as he left Christmas Day church services.

George was all smiles as the family departed Victoria during the Duke and Duchess of Cambridge's 2016 Royal Tour of Canada.

Up, up, and away! The young royal squished his nose against the window to check out the sights below as his family departed Victoria, British Columbia, on a seaplane.

A few days earlier, George clung onto his dad during a children's party for military families in Victoria, British Columbia. 

Thumbs up! George gave his stamp of approval at the Royal International Air Tattoo at RAF Fairford.

George basically broke the internet when he rocked his robe while meeting then-president Barack Obama at Kensington Palace.

Snow cute! Prince William and Kate Middleton and their bundled up kiddos, George and Charlotte, all flashed huge smiles during their family ski vacation in the French Alps.

While at his baby sister's christening at the Church of St. Mary Magdalene we couldn't help but laugh when we spotted George getting a little fussy when the royal family turned their attention away from him and onto Charlotte.

The then-toddler held on tight to his mom's hand as he walked on the grass at the Beaufort Polo Club in Tetbury, England, during the Gigaset Charity Polo Match.

George famously made his Buckingham Palace balcony debut in the same outfit his dad wore in 1984. Proving he was already ready for royalty, he at one point even turned around to wave to photographers. 

About a month after Princess Charlotte was born, mom Kate celebrated the arrival of her newborn by taking sweet snaps of her babies at their home. George seemed to have no problem fulfilling his big brother duties, sweetly cradling his baby sis in his arms.

Prince George joined his dad in waving to photogs when they arrived at the Lindo Wing at St. Mary's Hospital, where Kate had just given birth to his little sister, Princess Charlotte.

That face! The toddler's official Christmas photo, taken in a courtyard at Kensington Palace, a few weeks ahead of the holidays, was pretty much perfection. 

The first birthday calls for a big celebration, and that's exactly what Kate and William planned for George! At the time, British photographer John Stillwell followed the royal family to the Natural History Museum, and he snapped George a pic of the tot walking on his own at the "Sensational Butterflies" exhibition.

The then-8-month-old prince cuddled up on his mom's shoulder during the Duke and Duchess of Cambridge's stop at the Plunkett's Parent's Group at Government House in Wellington, which came during their royal tour of New Zealand and Australia.

One of George's first public appearances was when he was christened at the Chapel Royal in St. James's Palace. Kate and William were all smiles watching their first baby be blessed into the Church of England.
