She recently had a title upgrade, becoming Princess of Wales upon the accession of King Charles.
But when her husband Prince William eventually comes to the throne, she will receive another promotion.
Kate will become the Queen - the same as Camilla - and will probably be known as Queen Catherine, Catherine being her real first name.
When this happens, it is likely that Kate will have an even bigger platform on which to showcase the causes and organisations close to her heart.
And responding to a curious child during her recent visit to the Chelsea Flower Show, she was quizzed on the first thing she'll do when she takes the top job.
The question came from Saron Fikremariam, a pupil from one of 10 primary schools enjoying the inaugural children's picnic at the show.
The 11-year-old shared Kate's swift answer, revealing: "I asked her what's the first thing she is going to do when she becomes Queen and she said she is going to help kids."
Elsewhere on the trip to the Flower Show, Kate sat down to enjoy picnic time with the children, where she was quizzed by the youngsters about royal life, to which Kate replied: "You have to work hard".
She also offered the youngsters a glimpse of Prince Louis' school life, saying he has been growing broad beans in the school garden.
However, she revealed one thing she is not allowed to provide the public with as a souvenir of meeting her - despite it being a relatively simple request.
Keen to secure something to remember her by, some of the children asked the princess to sign her name on their drawings of the gardens.
But according to The Telegraph, she told them: "My name's Catherine. I'm not allowed to write my signature, it's just one of those rules."
However, not wanting to leave the children empty-handed she drew some sketches for them - including one of a flower, another of a tree and one of a pond surrounded by some plants.
Kate also met with ex-servicemen and women the Chelsea Pensioners, where a garden with a covered dining area has been created for them, alongside a kitchen that will produce meals for the elderly group from produce grown nearby.
"What's on the menu?" Kate asked as the pensioners tucked into chargrilled peas with herbs.
Harry Puttick, who served with the Royal Welsh Fusiliers for 30 years, replied gallantly: "The peas are forgettable, you are not."
With the cook nearby, he joked afterwards: "I'd better say the peas were wonderful, but it was fantastic to meet the future Queen."
She wore a vibrant bubblegum pink ME+EM dress that she previously wore in 2021 when meeting a five-year-old cancer survivor at the Palace of Holyroodhouse in Edinburgh.
