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.
