Her big brother Prince George is said to be able to count up to ten in Spanish at the age of three.
Additionally, another source said that Princess Charlotte has "beautiful manners" and "is so polite, but also fun and energetic".
"The images were taken by The Duchess shortly before Princess Charlotte left for her first day of nursery at the Willcocks Nursery School".
It's believed the reason for a different school is because the royal family was living in a different place at that time, and as all parents know, proximity is key.
Kate Middleton, 36, has revealed her daughter, Princess Charlotte, 2, speaks Spanish as well as her first language, English.
Metro reported that Princess Charlotte has been learning Spanish phrases from nanny Maria Teresa Turrion Borrallo.
The school charges fees of just over £3,000 a term, where it employs lots of play as children learn.
According to magazine, the precocious toddler, who is attending Willcocks Nursery School in Kensington, already speaks two languages - a skill most people can not claim.
The Duchess of Cambridge celebrated her 36th birthday earlier this week.
Despite being only two years-old, the younger sister to Prince George is already more accomplished than most of us.
