And she's off! Crown Princess Leonor took a moment to take some photos on her first day of school at UWC Atlantic College in Wales, England.
The future Queen of Spain looked trendy in a striped shirt, green jacket, jeans and white sneakers. The princess will also have a fellow royal at the school, as Princess Alexia of the Netherlands is set to attend this year, too.
Queen Máxima and King Willem-Alexander posted some photos of their daughter's latest venture on social media.
"Princess Alexia leaves for the United World College of the Atlantic in Wales. For the next two years she will be pursuing her International Baccalaureate. Princess Alexia completed the fourth year of the Sorghvliet Christian Gymnasium last school year," they wrote via Twitter.

The teen looked like she was making herself right at home!
"We are looking forward to welcoming HRH Princess Leonor of Asturias as one of the Spanish nominees to attend UWC Atlantic in 2021," Peter T. Howe, principal of the college, said earlier this year. "We hope very much she enjoys her time in Wales and have little doubt she will thrive as a member of our amazing community."
The college — which was founded in 1962 — is very popular among the royals. Queen Noor of Jordan and one of her daughters graduated from the institution, while Willem-Alexander also attended the university.
The college's mission “is to make education a force to unite people, nations and cultures for peace and a sustainable future.”
The 15-year-old will still maintain her public duties as heir to the Spanish throne, the Royal Household revealed.
Leonor is taking a two-year course to earn her International Baccalaureates.
We can't wait to see what else is in store for the princess!
