Prince George is officially five years old and to celebrate the milestone moment, the palace have released a heartwarming new photo of the smiling royal.
And it's the sweetest birthday portrait yet!
"The Duke and Duchess of Cambridge are very pleased to share a new photograph of Prince George to mark His Royal Highness's fifth birthday. Thank you everyone for your lovely messages," their statement read.
In the new photograph, the third in line to the British throne positively beams at the camera with his hands behind his back and a gorgeous grin on his face.
And if you were thinking Prince George's darling outfit looks familiar, you'd be right.
The birthday snap was captured in the gardens of Clarence House by Matt Porteous after Prince Louis' christening on Monday 9th July.
Porteous is of course the same photographer who photographed the magical moment between Duchess Catherine and Prince Louis after his christening and was released as a bonus pic.
Prince George will be celebrating his fifth birthday privately with his family on the island of Mustique as they enjoy their first holiday away with Prince Louis and The Middletons.
The first child of Prince William and Duchess Catherine, Prince George Alexander Louis of Cambridge (and his gorgeous chubby cheeks) entered the world on July 22nd, 2013.
It's been a jam-packed five years for the charming royal, who in his short time has become a loving big brother to Princess Charlotte and Prince Louis, a fashion icon, the world's number one spirit animal thanks to his huge range of sweet faces, plus he's found a fun royal playmate in cousin Savannah Phillips.
In 2014, George travelled to Australia and New Zealand with his parents on his first official royal tour. He's since joined mum and dad on trips to Canada, Poland and Germany.
The early years of his childhood were spent at the Cambridge's country estate, Anmer Hall, before they moved back to Kensington Palace in London full-time.
And last year, he reached another huge milestone as he started school at Thomas's Battersea in London.
According to proud parents, George has developed a strong little personality.
"George rules the roost and Charlotte isn't far behind," Prince William has said.
Wishing George the happiest of birthdays and many more years of joyful smiles!
