Meghan was "unresponsive" to Camilla's offerings of advice and support when she first joined the royal family, an explosive new book claims.
Being thrust into The Firm isn't an easy task - and both Camilla and Meghan know all too well the perils it can bring.
A new book, titled Camilla, Duchess of Cornwall: From Outcast to Queen Consort by biographer Angela Levin, reveals the new Queen Consort's upbringing and how she became one of the core members of the Royal Family.
It's thought that Camilla wanted to help any newcomer adjust to life within the family after discovering what a huge lifestyle change it can be.
Meghan, however, was described as "bored, unresponsive and preferred to go her own way" after Camilla's attempts to be supportive while taking her out for private lunches, according to claims in an extract of the book published in the Telegraph.
Camilla was of the view, the book claims, that she could help the Duchess of Sussex "find her feet" amongst the pressure of being shoved into the public eye and the scrutiny she would likely face.
An unnamed source told the book's author that Camilla “doesn’t want to see anyone struggling" and that "she is fond of Meghan".
Despite Camilla's attempts, however, Meghan didn't seem to change her attitude, according to Ms Levin.
Although, the royal biographer claims King Charles, who was Prince of Wales at the time, enjoyed Meghan's company as they discussed theatre and the arts.
When Meghan first joined the family, the Duchess of Sussex was thought to be an incredibly hard worker by the Royal Family.
One of her most notable examples early on was the cookbook she made contributions to which had been put together by survivors of the Grenfell Tower fire in 2017.
Later, Camilla invited the Duke and Duchess of Sussex, as well as Camilla's friend Lucia Santa Cruz, to lunch at Highgrove, and ensured the menu had been cultivated specifically from recipes in cookbook.
Lucia described this as "a really nice gesture", but it's claimed to have made little impact on Meghan.
In January 2020, when Harry and Meghan stepped down from their senior positions in the Royal Family, Camilla appeared to deal with it in the same manner as when she was verbally attacked in the 1990s - avoid talking about it and concentrate on supporting her husband, Charles.
A source is also quoted in the book as saying Prince Harry has recently been very negative about Camilla, but believes it “could be part of his therapy process to relive certain things and he may want to blame someone else for his own mistakes.
"As I understand it his father and stepmother have become hateful in his mind. I’ve also been told that Meghan has been horrible about her too".
Previously, Camilla offered the same sort of support to Kate Middleton, now Princess of Wales, when she was settling into royal life.
She is believed to have taken her through important details like customs, protocols and the restrictions that come with the territory.
It appeared to strike more of a chord with Kate, as one of her friends said: “Camilla’s exceptional warmth has really touched Catherine.”
The explosive biography also goes onto reveal how Camilla won over senior royals and that Prince Andrew didn't want Charles to be King.
The author and royal expert first met Camilla in 2015 and compiled the biography after speaking to her friends, staff and ex-colleagues.
The book also looks back on the former Duchess of Cornwall's rebellious years, detailing how she quit school in 1964 with just one O-level and was later "sacked on the spot" for arriving late to her receptionist job after a party.
It uncovers her unsteady journey to becoming accepted by the royal family, highlighting her contribution to charities and support during the Covid pandemic.
