Prince William and Kate have never spoken about their nanny, and only confirmed that she was working for them in a brief statement released back in 2014 after she was pictured pushing Prince George's pram around Hyde Park.

Who is Maria Teresa Turrion Borrallo?
Maria has been William and Kate's official nanny since Prince George was six months old. Back in 2014, Kensington Palace confirmed her full name, before adding that she was originally from Spain and had trained at Norland College, a childcare training college in Bath.

At the time, one of Maria's friends told HELLO!: "She has worked with other prominent high-society families in the past. It was from there that the Cambridges heard of her and hired her.

Where does Maria live?
Maria used to live with William, Kate and their three children until the family moved into Adelaide Cottage in Windsor.
