The young royals are growing up! After Prince George attended his first day of school in September, his little sister Princess Charlotte followed suit on Jan. 8 by attending her first day of nursery at the Willcocks Nursery School. "The Duke and Duchess of Cambridge are very pleased to share two photographs of Princess Charlotte at Kensington Palace this morning," Kensington Palace wrote alongside two precious photos of the 2-year-old posing for the camera. "The images were taken by The Duchess shortly before Princess Charlotte left for her first day of nursery at the Willcocks Nursery School." See the pictures, and get ready for cuteness overload!
