Prince Harry and Meghan Markle, the Duke and Duchess of Sussex have hired the third nanny for baby Archie Harrison since May. The nanny, whose identity hasn't been revealed yet, was spotted with the couple during their last holiday in Nice, France.

In photographs obtained by The Sun, the nanny can be seen along with Prince Harry and Meghan Markle on the private jet. This is the first time the royal baby's nanny was seen since the news broke that the couple had hired someone new to look after baby Archie.

She is reported to be the third nanny hired by the Duke and Duchess of Sussex since the birth of their son in May. The first nanny was allowed to leave, while the second only works in night shift.

The third nanny is reportedly helping the royals with the baby throughout the day. However, she doesn't live with the Sussexes in Frogmore Cottage. She is likely to travel with Harry, Meghan and baby Archie on their official visit to Africa this autumn.

Nannies have been an indispensable part of the royal family for decades. Princes William and Harry had many nannies when they were growing up, their favourite being Tiggy Legge-Bourke. Prince William and Kate also hired the Spanish nanny, Maria Turrion Borrallo, for Prince George when he was eight months old. The latter also helps look after Princess Charlotte and Prince Louis.

Meanwhile, in another development, the royals used social media to share a sneak-peek at Meghan's upcoming capsule collection of charitable workwear. The capsule collection will benefit Smart Works, one of Meghan's charities.

"TRHs The Duke & Duchess of Sussex posted a behind the scenes preview of the recent promotional shoot for HRH The Duchess of Sussex upcoming @SmartWorksHQ capsule collection," they tweeted.

Meghan has collaborated with Marks & Spencer, John Lewis, Jigsaw, and Misha Nonoo for the collection. The workwear collection launches this fall.
