Prince George Turns Five: See His Adorable Birthday Photo

Prince George, the future king of England, is celebrating his fifth birthday on Sunday, and his parents, Prince William and Kate Middleton, have released a new photo to mark the occasion.

The photo was taken in the garden of Clarence House by photographer Matt Porteous after the christening of George's baby brother, Prince Louis.

In the photo, Prince George is sporting one of his biggest smiles yet, despite recently showing his shy side.

Dressed in a short-sleeved white shirt with a Peter Pan collar and blue piping paired with blue shorts by Amaria, the young prince looks charming as ever.

This isn't the first time Prince George has been in the spotlight.

He and his younger sister, Princess Charlotte, have taken centre stage at several royal events this season.

They stole the spotlight when they went to visit their new baby brother, Prince Louis, in the hospital after he was born in April.

They also played the roles of page boy and bridesmaid at Uncle Prince Harry's royal wedding to Meghan Markle, and unexpectedly got attention for their palace window antics during the Royal Air Force anniversary flypast.

Prince George's parents have released official portraits for every one of his birthdays.

When he turned one, they shared beautiful photos of the future king and his parents taken at London's Natural History Museum in a butterfly exhibit.

For his second birthday, they released an adorable photo taken by Mario Testino on the day of Princess Charlotte's christening.

The candid shot captured a fun moment between father and son.

On his third birthday, they released four too-cute photos of chubby-cheeked George standing on a swing, walking in the garden and playing with a family dog, Lupo.

And for his fourth birthday last year, Will and Kate shared an adorable photo of George, complete with toothy grin, taken at the royal family's home of Kensington Palace.

Prince William and Kate Middleton are very proud of their son and are thrilled to share this new photo with the world.

The young prince has already shown that he knows how to charm a crowd, and with his infectious smile, he is sure to win over many more hearts in the years to come.
