Prince George, the eldest son of Prince William and Princess Catherine, has officially become a teenager. Kensington Palace has shared a new photo of Prince George wearing a suit without a tie. As the future king, Prince George will take the throne after his father and grandfather, King Charles III. The photo was taken by Matt Porteous in May after the Trooping the Colour ceremony. Prince George will start high school in September and will attend Eton College, a prestigious school that his father also attended. We wish Prince George a happy birthday and look forward to seeing what the future holds for him!
