The Princess of Wales has a group of close-knit friends, particularly near her Norfolk home - including Rose Hanbury, the Marchioness of Cholmondeley.
It wasn't until Rose had settled down with her husband, David Cholmondeley, 7th Marquess of Cholmondeley, that Rose and Kate first became acquainted. But how much do you know of Rose, her past, and her friendship with the royal mum-of-three? Read on to find out all you need to know...
Rose's early years
Rose was born on 15 March 1984 as the second daughter of Timothy Hanbury, a web designer, and Emma Longman, an interior designer, and she grew up with two siblings, her older sister Marina, and younger brother, Dave. Rose was also the granddaughter of Lady Elizabeth Lambart, a bridesmaid at the wedding of the late Queen and Duke of Edinburgh.
She was educated at Stowe School in Buckinghamshire, which charges £38,000 a year, before obtaining a degree from the Open University.
Rose's career
After her graduation, Rose pursued a career in modelling, signing with agency Storm, who has previously signed legendary stars like Kate Moss and Monica Bellucci.
During her modelling career, she ended up courting a small political storm when she and her sister were pictured wearing bikinis next to the then prime minister, Tony Blair, at the infamous Villa Cetinale.
Following her stint as a model, Rose embarked on a very different career path, as she found work as a parliamentary researcher for Conservative politician Michael Gove. She resigned from her role ahead of giving birth to her twins.
Her friendship with Kate and Prince William
Rose and Kate are believed to have begun their friendship following the model's marriage to the Marquess of Cholmondeley, as their home, Houghton Hall, is just a 15-minute drive away from Sandringham. Their bond strengthened after William and Kate were gifted Anmer Hall and began spending more time in Norfolk.
Rose and David were guests at Kate and William's royal wedding in 2011, and later in 2016, they also teamed up to host a gala dinner in support of East Anglia's Children's Hospices' nook appeal at Houghton Hall. The couple were also seen among the guests at Sandringham on New Year's Day in 2020, when Kate reportedly hosted a party for her 38th birthday.
While there were reports of a fall-out in 2019, Kate was one of the guests at the annual festival hosted by Rose and her husband last summer.

One of the couple's sons, Oliver, also served as a page of honour at the coronation of King Charles in 2023.
Rose's husband and family life
During her time as a model, Rose met her husband David and the pair embarked on a whirlwind romance, announcing their engagement in June 2009. The next day it was revealed they were expecting twins and just a day later, they tied the knot at a Chelsea registry office. The couple have three children, 14-year-old twins Alexander, Earl of Rocksavage and Oliver, Lord Cholmondeley, and seven-year-old daughter Lady Iris.
The Marchioness lives with her husband and children at the Palladian Houghton Hall in Norfolk, just over three miles away from Kate and William's country home Anmer Hall. David, 63, inherited an estimated £112million estate in 1990, which includes Cholmondeley Castle in Cheshire.
