Rose Hanbury has entered the chat.
Amid the unfolding Kate Middleton drama an additional player has appeared, sending social media off on another tangent of unfounded gossip and conspiracy theories.
In Britian’s aristocratic circles she’s known as Lady Rose Hanbury, the Marchioness of Cholmondeley (pronounced “Chumley”), and has long been linked to the British Royal Family through her well-heeled family and their prestigious place in British high society.
For years, the royal gossip mill has speculated that Hanbury is Prince William’s alleged mistress, though it has never been proven. Rumblings of a possible affair first surfaced among royal watchers in 2019 and now, amid wild speculation of the Princess of Wales’ whereabouts and a series of missteps by the Kensington Palace PR machine, her name has resurfaced in connection with the drama.
The rumour kicked into high gear this week. The Late Show host Stephen Colbert even addressed it in his opening monologue on Tuesday night’s show. (You can watch below.)
Here’s what you need to know about Lady Rose, how she’s connected to the royal family and how these resurfaced rumours have been given new life.
How are the Hanburys connected to the Royal Family?
Sarah Rose Hanbury was born on March 15, 1984 to her parents, Timothy Hanbury and Emma Longman. She is one of three children, with an older sister and a younger brother.
Timothy and Emma were both designers: she worked in fashion and interior design, while he worked in website design.
Long before Rose Hanbury was connected to the Prince and Princess of Wales, the family was connected to the royals. Her maternal grandmother, Lady Elizabeth Lambart, was one of Queen Elizabeth II’s bridesmaids at her 1947 wedding to Prince Philip.
Hanbury attended a prestigious boarding school and upon graduation undertook an Open University degree and began working as a model at the age of 23.
Around this time, she met her now-husband, David George Philip Rocksavage, 7th Marquess of Cholmondeley. The pair started dating in 2006, causing a bit of a stir, as he is 23 years her senior.
Hanbury and Rocksavage announced their engagement in June 2009 and wed two days later. Just a few months later, in October of 2009, they welcomed twin boys into the world, who were born prematurely ahead of their January 2010 due date. A baby girl, Iris, was born a little less than seven years later.
Hanbury’s connection to William and Kate
The couple is said to have struck up a friendship with the young royals after they settled into the palatial Houghton Hall, which is right down the road from the royal estate, Sandringham.
It’s believed Hanbury and Middleton became fast friends when Middleton would visit her future husband at Sandringham. Later, when William and Middleton moved into Anmer Hall on Sandringham Estate following their 2011 wedding, the Cambridges and Cholmondeleys developed a strong friendship.
Living a stone’s throw from the royal couple earned the Marchioness an invite to a number of royal functions over the years. In 2017, she was spotted sitting next to Prince Harry at a Buckingham Palace state banquet and in 2022 she attended the memorial service for Prince Philip and the funeral for Queen Elizabeth.
In April 2023, it was announced that their son Oliver would serve as one of the pages at the coronation for King Charles, alongside heir to the throne, Prince George.
Igniting the rumour mill
In 2019, rumours of a rift between Hanbury, William and Middleton began circulating, with the tabloids claiming the royal couple had a falling out with the Marchioness.
Around the same time, rumblings of an alleged affair between the Prince and Hanbury began popping up after a British tabloid published a story claiming that William cheated on his wife while she was pregnant with Prince Louis.
Kensington Palace has denied those rumours, but with this month’s speculation into Middleton’s health, the rumours have gained a new foothold.
William, Middleton and Hanbury have never directly addressed the claims, allowing the rumours to fester and take on a life of their own. Throughout history British royal mistresses and affairs have been well documented, but infidelities are rarely addressed by those participating.
Royal expert Omid Scobie told Entertainment Tonight last year, ahead of his royal biography Endgame: Inside the Royal Family and the Monarchy’s Fight for Survival, that he hasn’t “(seen) proof that there is more to this than just tittle-tattle.”
He added that because the rumours have never been addressed head-on, it’s likely they will “never go away.”
“Unfortunately, if a rumour is left to kind of do its own thing, it can run 20 laps around the world before you even think about what, how you want to kind of address it,” he said. “They never addressed it, so those rumors will never go away even though there’s no truth to suggest that they are true.”
