Prince George is officially 12 years old — and to mark the occasion, the Prince and Princess of Wales have released a brand-new birthday portrait of their eldest son.

The image, shared on social media with the caption “Happy 12th Birthday to Prince George!”, has royal watchers in disbelief over just how grown-up the young prince looks.

As the second in line to the throne, George has been in the spotlight since birth. But fans say it still feels like “just yesterday” that he was a toddler in his father’s arms. “Can’t believe he’s 12!” one Instagram user commented. Another wrote: “Happy Birthday to our little (not so little anymore) Future King!”

The new image follows the tradition the royal family has kept in recent years — releasing official portraits for their children on birthdays. Charlotte’s 10th birthday portrait was shared back in May, with fans noting how much she resembles her father, Prince William. Meanwhile, Prince Louis’s portrait in April had people amazed by how fast he’s growing.

Each new photo release becomes a mini event for royal fans — and a moment of shared nostalgia as they watch the next generation of royals grow up before their eyes.

Why the royal family shares portraits — and what they mean

Though it might seem like a simple birthday post, these portraits serve a deeper purpose for the royal family.

Royal birthdays, especially those of senior family members and direct heirs, are treated as national milestones. The release of official portraits not only allows the public to celebrate alongside the royals, but also helps maintain a personal connection between the monarchy and its people. Each photo becomes part of the historical record, capturing the evolution of a royal life — much like presidential portraits mark time in office.

And as Prince George steps into his teenage years, he may soon face another royal tradition: traveling separately from his father on official visits. The practice, while rare for young royals, has historically been used to protect the line of succession. If anything were to happen during travel, the rule ensures that not all immediate heirs are on the same flight — a precaution rooted in continuity and royal stability.

For now, though, Prince George seems content celebrating his big day just like any other 12-year-old — with cake, family, and millions of people wishing him well.

Happy Birthday, George — here’s to another royal year ahead.
