Princesses Eugenie and Beatrice are reportedly threatening to cut off their parents, Andrew Mountbatten-Windsor and Sarah Ferguson, as rumours swirl about the former couple’s latest attempted cash grab involving Princess Diana.

Andrew and Sarah are already receiving intense scrutiny over their links to convicted pedophile Jeffrey Epstein, which has resulted in Andrew being stripped of his Prince title and booted out of the Royal Lodge at Windsor.

Beatrice, 37, and Eugenie, 36, have reached tipping point with their parents who are reportedly in publishing negotiations about a ‘tell-all’ memoir about the late Princess Diana, according to New Idea.

“This will be the last straw for them,” a royal insider said.

“They’ve had enough and can’t believe they would stoop so low as to try and cash in on their late aunt.”

The sisters are “united” in their threats to estrange themselves from their parents, and will even go as far as preventing them from seeing their grandchildren in response to the memoir.

“They’re doing everything they can to stop this desperate and tasteless move, including banning them both from seeing their grandkids,” the source said.

“It will certainly put their already fragile relationship with William and Kate at risk.”

Eugenie is currently pregnant with her third child, and has two boys with her husband Jack Brooksbank: August, five, and two-year-old Ernest.

Beatrice and her husband Edoardo Mapelli Mozzi share two daughters, Sienna, four, and 18-month-old Athena.

The sisters have been implicated in their parents’ association with Epstein, especially their father, who appeared to be a close associate with the financier before his death in 2019.

It appears Beatrice and Eugenie have the backing of their uncle King Charles, who has also publicly distanced himself from Andrew since he ascended the throne.
