A new photograph of Prince George has been released by Kensington Palace to mark the royal’s 13th birthday.

The photo, showing a relaxed George standing with his hands in his pockets and wearing an open-necked white shirt and dark suit, was shared by the Palace on social media.

The portrait was captioned with a message that read: “Happy 13th birthday, George!” alongside an emoji of a party popper.

The latest picture was snapped at Kensington Palace last month on the same day as the iconic Trooping of the Colour ceremony.

It was taken by Matt Porteous, who has captured many other images from Prince William and Prince Kate’s family celebrations.

George, the eldest son of the Prince and Princess of Wales, is second in line to the throne.

Ahead of his milestone birthday today, a friend of the royals spoke to The Telegraph and revealed some insight into the teenager’s personality.

“There are challenges, but they have been absolutely consistent about putting the family at the heart of everything they do, and the public supports them.”

Meanwhile, after months of speculation, a major decision was made about Prince George’s future in June.

Kensington Palace confirmed that the 13-year-old will follow in his father’s footsteps and attend the prestigious Eton College when the UK school term begins in September.
