The Prince and Princess of Wales released a sweet new portrait of their son, Prince George, to mark his 12th birthday on Tuesday.
The snap, taken by Josh Shinner, shows second-in-line to the throne George in Norfolk.
The young prince is dressed in blue checkered shirt and an olive green gilet.
The caption read: "Happy 12th birthday to Prince George!"
Royal fans flooded the comments section with well-wishes for George, with many remarking that the young prince is his dad, Prince William's doppelganger.
"He is his father's clone!" One commenter wrote underneath the portrait.
"What a fine young man he's become - handsome, poised, and full of quiet confidence," another royal fan commented.
"Eyes like Grandpa Middleton, but the smile of his father," a third added.
"At 12, George is entering his final year at Lambrook before moving on to secondary school, so this will be a key year for him. But William and Kate have always prioritised giving their children as normal and private a childhood as possible, and that is not about to change. Prince George is second in line to the throne, however, so they will be gently showing him the ropes of royal life. We saw that when he joined his parents at the tea party for veterans at Buckingham Palace - it was a great opportunity to introduce George to royal engagements in a familiar place, while surrounded by his family," says HELLO!'s Royal Editor Emily Nash.
"We've also seen how George is able to enjoy plenty of experiences that other children his age love - joining his dad to watch the football and going to concerts - even if he did get a VIP meet and greet with Taylor Swift!
"At 12, William stopped flying with his father, as a precautionary measure, to protect the line of succession. It may be that William and Kate choose to do things differently when it comes to their own family, however."
While the Princess of Wales has traditionally taken the official birthday portraits of her children, the photograph released of Prince Louis on his seventh birthday in April was captured by photographer Josh Shinner.
And in royal first, the birthday snap of Princess Charlotte hiking in Cumbria released in May, was taken by mum Kate on her iPhone.
The Prince and Princess of Wales are currently taking a break from their royal duties as they enjoy quality time with their children during their school summer holidays.
George was last seen publicly as he and Princess Charlotte attended the Wimbledon men's final with William and Kate on 13 July.
Prince George's early life
Prince George Alexander Louis was born in the private Lindo Wing of St Mary’s Hospital, Paddington, London, at 4.24pm on 22 July 2013, weighing 8lb 6oz.
He made his debut in front of the world's media on the hospital steps one day later, wrapped in a white merino wool shawl, cradled in his mother's arms.
George spent the first few months of his life in Anglesey, Wales, where William was stationed at the RAF base, before the family moved into Apartment 1A at Kensington Palace.
The little prince undertook his first royal tour to Australia and New Zealand at just eight months old.
In May 2015, he became a big brother to little sister, Princess Charlotte, and the family relocated to Anmer Hall in Norfolk.
George began attending West Acre Montessori School Nursery in January 2016.
By the time the prince was ready to start school, the then Cambridges had already moved back to London.
George and Charlotte both attended Thomas's Battersea School until 2022 when William and Kate relocated their family to Adelaide Cottage in Windsor.
Their children have been attending Lambrook School in Berkshire since September 2022, with George set to move to his next school in 2026.
