Despite having no relationship with her for 20 years

Meghan's Estranged Sister Samantha Markle Says Harry and Meghan "Ending In Divorce"

Meghan's father Thomas Markle is not the only Markle profiting off of Meghan's name. Meghan's half-sister Samantha is also bashing Meghan while claiming she wants relationships to be mended. Now the sister who has written an entire "tell-all" book about the sister she only met a handful of times is making bold claims.

Thomas Markle's interview on Good Morning Britain left a bad taste in viewer's mouths after he admitted to lying to his daughter and selling stories to the tabloids. He threatened his daughter and her husband, Prince Harry, saying he would continue to sell stories "for the press. If I don't hear from them in 30 days, I'll do another story from the press."

Now his daughter Samantha Markle is reaching out to countless media outlets like radio shows and TMZ to make disparaging claims against her half-sister.

Thomas's other daughter Samantha Markle (previously Samantha Grant) has also decided to write a "tell-all" book about Meghan titled The Diary of Princess Pushy's Sister. Meghan explained to Oprah during Oprah with Meghan and Harry that she was not raised with Samantha and that "It would be very hard to tell-all when you don't know me." Meghan did not grow up with her half-sister 17 years her senior.

"I grew up as an only child... The last time I saw her must have been at least 18-19 years ago and 10 years before that."

"She changed her last name back to Markle when she was in her early 50's at that time, only when I started dating Harry. So I think that says enough."

According to TMZ Samantha took to an Australian radio show Fifi, Fev & Nick to say: "When she said 'I lost my dad' -- the world watched as my dad was in interviews wanting communication with his daughter. She didn't lose her dad. She iced her dad!"

"I feel sorry for Harry. He fell victim to her negligence, and I will say sociopathy ... she pulled him away from his family, all of his friends, the life that he knew."

Samantha Markle Says Harry & Meghan Are "Ending in Divorce"

Samantha has just spoken with TMZ about her "inside" opinion of the future for her half-sister Meghan Markle and Prince Harry. She said, "I see it ending in divorce unless they get extensive counseling and can agree to work on being honest, to work on apologies to everyone that they've damaged in the course of this bull-in-a-china-shop, two-year spiel."

The Duke and Duchess of Sussex attend an event at Canada House in London, UK to mark Commonwealth Day on March 11th, 2019.

She also suggests Harry is "already questioning [the marriage]. He has to be if he has a functioning frontal lobe! Come on! He's not 12, he was in the military, he's got to have a sense of 'Oh my God, everything you've said to me is a lie. What man would be happy or comfortable like that."

While the two have not had a relationship for years this doesn't seem to stop Samantha Markle from giving her "inside" two cents to as many media outlets as she can and promoting her tell-all book The Diary of Princess Pushy's Sister.
