As one of the most senior women in the royal family, Kate Middleton has now been given the honourable title of Princess of Wales.
Those closest to the royal including her husband Prince William and her family simply refer to her as her birth name Catherine or simply Kate, the Mirror reports.
However, it's been revealed that the Princess was also previously referred to by a cruel nickname that mocked her mother Carole Middleton which William's 'snooty' friends created before the couple tied the knot.
According to royal expert and author Katie Nicholl, people would whisper "Doors to Manual" at the future princess which was a mocking reference to Carole's former career as a British Airways flight attendant.
Speaking on the Vanity Fair Dynasty podcast, Nicholl said: "To her full credit, Kate never rose to it - the snootiness of the upper classes levelled at what they called the en-masse Middletons."
Meanwhile an aide previously revealed to the Sunday Times Magazine that Kate was aware of the nickname and didn't like being called it but rose above it and refused to let it bother her.
They said: "It was never water off a duck's back, but she has extraordinary strength of character and resilience. I've never once seen or heard of her losing her temper."
Now, after being married to William for 12 years and the couple settling down with their children Prince George, Princess Charlotte and Prince Louis, Kate is now one of the most important members of the royal family and will be future Queen one day.
The Princess of Wales attended the Chelsea Flower Show earlier in the week and gave a very honest five-word reply when a schoolgirl asked her what life as a royal was like.
Kate joined school kids touring some of the attractions including a walled kitchen garden designed by Mark Gregory.
The royal was also seen sitting down to enjoy a picnic with the children where the youngsters quizzed her about her life as a Princess to which Kate candidly replied: "You have to work hard".
She also gave the kids a glimpse into her youngest son Prince Louis' school life, saying he has been growing broad beans in the school garden before she showcased her artistic talents by sketching flowers and plants for the kids instead of a signature.
The royal also met with ex-servicemen and women the Chelsea Pensioners, a feature of Gregory's garden and a covered dining area was established for them, alongside a kitchen that will provide meals for the elderly group using produce grown nearby.
When Kate asked the pensioners what the dish was as they tucked into chargrilled peas with herbs, Harry Puttick, who served with the Royal Welsh Fusiliers for 30 years, charmingly replied: "The peas are forgettable, you are not."
With the chef nearby, the cheeky OAP added: "I'd better say the peas were wonderful, but it was fantastic to meet the future Queen."
