Prince George has turned 13, reaching a new milestone as the eldest child of Prince William and a senior young member of the British royal family. The birthday marks his move into his teenage years while he remains second in line to the throne.

Kensington Palace marked the occasion by releasing a new picture of the prince. Birthday wishes also came from King Charles III and Queen Camilla, highlighting the family significance of the day.

The moment comes as Prince George prepares for another major change: the start of his education at Eton College. The school is closely associated with Prince William, and the next step has drawn attention as George begins to follow a similar path.

As the eldest child of the heir to the British throne, Prince George has long been watched as part of the monarchy's next generation. His 13th birthday brings together the personal celebration of becoming a teenager and the public interest surrounding his future role.
