Our favorite little prince just turned four and returned home to celebrate after accompanying his parents and sister Princess Charlotte on their five-day trip to Poland and Germany. While we haven’t yet heard of any party details, Kensington Palace did release an official photo of the prince. Beaming from ear-to-ear and sporting a band-collared striped button down, he looks absolutely adorable—and bears a strong resemblance to his father. Wishing Prince George the happiest of birthdays!
