Half-sister Samantha Markle, 56, is releasing her memoir, titled The Diary of Princess Pushy’s Sister Part 1. It is set to be released on January 17. The Duchess of Sussex’s sister has been critical of Meghan in the past.
A source claimed to In Touch Weekly that Meghan is “sick to her stomach” but “won’t act bothered or upset about it in public”.
Samantha has said the book was not written to attack Meghan, 39.
She told US Weekly: “Contrary to troll gossip and aggregate news rumours, my book has never been designed to attack my sister.
“It’s relatable. There’s a lot to learn – the good, the bad and the ugly.
“I’ve been very forthcoming that I was never writing a hardbound tabloid.”
Meghan’s father, Thomas Markle, has also praised Samantha for her new book, which is 328 pages long.
According to bookshop Barnes and Noble’s website, the memoir will expose the truth about Samantha’s life “as a royal fairytale plummets from the tea towels”.
The book’s overview read: “Amidst a firestorm of fake news and media mayhem, Samantha Markle shares the truth about her life and family against all odds and ultimatums, as a royal fairytale plummets from the tea towels.

A source told the Mail on Sunday: “Meghan has some experience as a writer and used to have a popular blog called The Tig before she met Harry that covered health, travel, food and fashion.
“Fiction is something she has always wanted to try her hand at, and she could be assured that anything she writes would sell well, regardless of its quality.
“Fiction, be it children’s books or adult, would be a powerful way of conveying the messages of their woke brand.”
