Adorable Princess Charlotte is preparing for the next big step in her life as she is set to start school later this week.
The royal will join the reception class at Thomas's Battersea in south west London on Thursday.
Prince George is already a pupil at the £19,287-a-year private school so he will be there to keep an eye out for his little sister.
Her parents the Duke and Duchess of Cambridge will be dropping her off at the school gates with all the other mums and dads, MirrorOnline reports.
But when Charlotte sits down at her new desk and listens to the register for the first time - what will she actually be called?
Her full name is Charlotte Elizabeth Diana, and her official title is Her Royal Highness Princess Charlotte of Cambridge.
Both of these are a bit of a mouthful, and we can't imagine the kids in the playground or her teachers using them.
It's likely that Charlotte will follow in the footsteps as her older brother and other members of the Royal Family and use her parents' titles as her surname - Cambridge.
She will probably be known as Charlotte Cambridge to her peers, in a similar style to her brother who is believed to be George Cambridge.
However the prince's friends have come up with an adorable nickname for him - PG.
Her dad William and uncle Prince Harry did the same, using Charles's title - Wales - as their surname.
As well as using the name at school they both used it during their military careers.
