ABC News' Katie Kindelan and Carolyn Durand report:
There is a new woman in Prince George's life and she's preparing the young royal for a major milestone.
Palace officials confirmed today that Maria Teresa Turrion Borrallo has been hired as the nanny to George, the son of Prince William and Duchess Kate, who will turn 1 in July.
Borrallo, who is working for the family full-time, will join William, Kate and George on their trip to Australia and New Zealand in April, their first formal overseas trip as a family of three since George's July 22 birth.
The only additional detail released by the palace about Borrallo is that the woman now in charge of the third-in-line to the British throne was trained at Norland College, a nanny training college in Bath, England, known as one of the best in the world.
"We will not be giving further details on Maria or her employment, except to say that The Duke and Duchess are of course delighted she has chosen to join them," the palace said in a statement.
William, 31, and Kate, 32, had previously employed Jessie Webb, the same nanny who cared for William and his younger brother, Prince Harry, when they were young.
Webb, who came out of retirement to care for Prince George, was spotted last September stopping at a McDonald's with Kate and George as the trio made their way back to London.
The royal couple most recently appeared together, without Prince George, a t the Irish Guards' annual St. Patrick's Day Parade in Aldershot, Hampshire. The couple appeared tanned and relaxed after their week-long vacation in the Maldives.
