Kate Middleton and Prince William are currently in th US ahead of the Earthshot Prize awards ceremony on Friday night. But, while the pair tour around Boston, meeting the likes of President Biden among others, many royal fans are wondering who is looking after the Wales children while their parents are away.

Sadly, due to school term times, nine-year-old Prince George, seven-year-old Princess Charlotte and four-year-old Prince Louis couldn't join mum and dad on their international trip, meaning they've remained at their Windsor Estate home under the watchful eye of their long-term nanny – Maria Teresa Turrion Borrallo.

Spanish born Borrallo has been the Cambridge's live-in nanny since 2014, joining their team when Prince George was just eight-months-old. Prior to that she studied at the prestigious Norland College in Bath, and has "worked for other high-profile families" according to an insider who spoke to HELLO!. In fact, it was her experience as a nanny for other families that caught Kate and William's attention. "It was from there that the [then] Cambridges heard of her and hired her," the source added.

Speaking about Borrallo, the insider went on, "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."

As for how the Prince and Princess of Wales prepare their children for their time away, Prince William recently revealed they have a sweet family tradition. "They are always asking us where we are going," William said during a visit to Wales earlier this year, when asked by a member of the public about how the kids are doing. "And we show them where we are on the map," he added, per People.

We can't wait to see all the pics from their trip over the next few days!
