Meghan Markle's half-sister will soon release a tell-all book that she says will make the Duchess of Sussex "uncomfortable".
Samantha Markle, 56, will release The Diary Of Princess Pushy's Sister Part 1 in the US on Friday, after announcing she was writing the memoir in 2016.
"There was a lot going on behind closed doors that the world didn't know," Samantha told The Sun.
In the book's overview, the Duchess' sister promises it will expose the truth about her life and family "against all odds and ultimatums, as a royal fairytale plummets from the tea towels".
"There is something in it for everyone. It has been an interesting journey. It deals with my life and my perspective on several issues in the road as they intersect with this royal event in history," Samantha said.
Samantha has previously condemned Meghan's character in media interviews, calling her a "shallow social climber", "inhumane" and "the Duchess of Nonsense" - even accusing her of freezing out family members.
Meghan, 39, currently resides in a Santa Barbara mansion with Prince Harry and their one-year-old son Archie. She has previously labelled the claims "absurd", saying her half-sister hardly knows her.
Samantha told The Sun that the book is "fair and balanced".
"Naturally, some things she will like and some things she won't."
Samantha first revealed her intentions to write a memoir in April 2016 when Meghan's romance with Prince Harry became public.
According to the Daily Mail, Meghan is thought to have last seen her sister, who lives in Florida, in 2008.
