Prince William drove Prince George, Prince Harry and Kate Middleton to Buckingham Palace Tuesday to attend Queen Elizabeth II's annual Christmas lunch. Prince William told attendees that his 3-year-old son has started to realize what Christmas means for him. "He just said [Prince] George definitely knows it's Christmas this year because the presents are about and he's more into opening them than anything else," DJ AJ King told reporters of his conversation with Prince William.
