It was a full-on royal family affair as Princess Charlotte headed off to her first day of school on Thursday.
Charlotte was accompanied by her parents, the Duke and Duchess of Cambridge, and her big brother, Prince George, as they arrived at Thomas's Battersea school in London.
The 4-year-old princess joins her 6-year-old brother as students at the private school just a few miles from Kensington Palace.
The head of the lower school greeted Charlotte and the rest of the royal family before they headed inside. Prince William remarked that Charlotte is "very excited" about the first day of school.

And while she has a formal title, Charlotte will be known as Charlotte Cambridge at school, Vanity Fair reported.
Prince Louis, who just turned one-year-old earlier this year, did not join the family on the trip to drop off Charlotte and George.
