Prince George is officially a teenager! Kate Middleton and Prince William’s oldest son turned 13 on July 22, and the royals released a new portrait to celebrate the big day.
The Prince and Princess of Wales posted a photo of their teen son on Instagram, adding the simple, straightforward, yet sweet caption, “Happy 13th Birthday George.”
Unlike his 11-year-old little sister, Princess Charlotte (who posed outdoors in a field of flowers, dressed in a casual striped sweater and jeans) and eight-year-old younger brother Prince Louis (who wore a blue knit zippered sweater), George’s Bday pic has a much more mature look. And of course, that is fitting now that he is 13.
What did the Prince wear in his official royal 13th birthday portrait? George is going full GQ in a stylish black suit paired with a classic white button-down.
Fans of the royal family took to Instagram to wish the young prince well on this milestone birthday. And of course, no one can believe that Kate and William’s baby is a full-fledged teen.
One commenter referenced a 19-day tour that the family took back in 2014: “How on Earth is he already 13? Wasn’t he just in New Zealand and Australia with his many facial expressions? Happy Birthday not so little Prince George,” and another wrote, “He was once Baby Cambridge with those chubby, rosy cheeks, and now has grown into a young man. Time flies! Happiest birthday to our Prince George!”
But the comments didn’t end there. Based on the responses, almost all of the royal watchers are shocked that George is suddenly a teen: “Can’t believe he’s a teenager!”, “It’s hard to believe little Prince George has grown into a teenager!” and “Where did those 13 years go?”
Some reminisced about the day he was born: “I was outside the Lindo hospital wing the minute he was born, will never forget the crowds and photographers all wanting to be the first to know of George’s birth.”
Now that he’s a teenager, George will take the next step and start secondary school this fall. Like his father, Prince William, George will attend Eton College.
In June, royal biographer Sally Bedell Smith shared her insights into the royal family’s choice, telling PEOPLE, “Eton was a much-needed haven for William.” She continued, “It will give George a rigorous education that he will need for his role.”
The Prince isn’t the only royal to have a birthday in July. His grandfather,King Charles III’s wife Queen Camilla, turned 79 on July 17.
