The future king of England is growing up. Thursday will mark Prince George of Cambridge's 8th birthday, as the third in line to the British throne continues to grow, looking more and more the spitting image of his father, Prince William. The evening before, Kensington Palace released a new photo of the smiling young royal, who is seen perched on a Land Rover and dressed in a casual striped shirt. The picture was taken in Norfolk, where the queen's Sandringham estate is located and the Cambridges have a country retreat, Anmer Hall. Tradition has dictated the royals release new photos to commemorate family members' birthdays each year: Will and Kate have previously shared special shots of their three children on each of their birthdays, a custom they started on George's first birthday. Harry and Meghan have created an amended version of that tradition since stepping down as senior royals and moving to California. #royal #princegeorgeofcambridge #princewilliam #duchessofcambridge
