All hail his royal highness, the king of cuteness. Prince William and Kate Middleton — more formally known as the Duke and Duchess of Cambridge — released three adorable new photos of their son, Prince George, for the holidays on their official website. The rosy-cheeked prince posed for the photos at the end of November on the steps of Kensington Palace. For a 1-and-a-half-year-old, he pulls off a classy pair of knee socks and sweater vest with amazing flair — as well as a smize that would make Tyra Banks jealous.
