Meghan Markle's Half-Sister Releasing Tell-All Memoir 'Diary Of Princess Pushy's Sister’ Next Week

Meghan Markle's half-sister, Samantha Markle, will be dropping her tell-all memoir about the Duchess of Sussex and their family this month after years of teasing its release.

Markle's half-sister made headlines back in 2017 when she announced that she was writing a tell-all book about growing up with the actress-turned-royal. Now, after over three years, the memoir is materializing.

Samantha's "The Diary of Princess Pushy's Sister Part 1" can now be pre-ordered on Barnes & Noble, which is publishing the memoir, for $17.99. The book will be available on Jan. 17.

"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 fairy tale plummets from the tea towels. Sometimes the truth really is stranger than fiction," the book overview read.

Her official author bio on the Barnes & Noble website describes Samantha as an "author, screenwriter and counselor, as well as being the sister of the first modern American duchess."

"Having battled MS in a wheelchair for most of her adult life, she's no stranger to challenges or tenacity. With one screenplay in pre-production and her first book completed she continues to roll uphill as a 'squeaky wheel,' inspiring others and defending truth, in spite of stereotypes and 'fake news,'" the description continued.

Meanwhile, Samantha previously branded Markle a "shallow social climber." She also accused the duchess of freezing out their dad, Thomas Markle Sr., and the other members of their family after her relationship with Prince Harry turned serious.

However, two of their relatives came forward when Samantha announced her tell-all book, claiming she only wrote it to spite the former "Suits" actress due to her jealousy and hatred toward Markle.

“She’s just been overall jealous of Meghan as soon as she got famous and began taking jobs like, for example, [‘Beverly Hills’] ‘90210.’ And of course, when she got ‘Suits,’ that set her off,” Noelle Rasmussen, Markle’s niece and Samantha’s daughter, was quoted by Daily Mail as saying. “After however many years, she’s just completely bashed Meghan, said the most horrible things about her to the entire family, and just been completely jealous of her.”

However, Samantha claimed in a previous interview that there was no rift between her and Markle and that she was misquoted when she announced her book, denying that it was a "slamming tell-all."

"Well, it is true that I'm writing a book and the title is accurate, what is not true [is] this unbelievable swell that's been created that it's some sort of slamming 'tell-all,'" she said. "First of all, it's only a tell-all in that I go through and recant some of the beautiful nuances of our lives, our family home."
