As Duchess Catherine and Prince William are on their 2021 tour of Scotland, royal fans are curious as to who is looking after Prince George, Princess Charlotte and Prince Louis.

The family have access to staff that are familiar with each of their children and they can't travel along with their parents as they have school and nursery commitments.

British publication HELLO! was curious as well and revealed that the children have a live-in nanny called Maria Teresa Turrion Borrallo, who has looked after the children since 2014.

An insider said to HELLO! that Borrallo "worked for other high-profile families and it was from there that the Cambridges heard of her and hired her".

"She is not married and doesn't have a boyfriend, as her life is totally dedicated to the family she is working with. She is known for being totally professional – married to the job."

The tour of Scotland is the couple's first engagement outside of England in five months and they're attending various engagements over the tour.
