Meghan Markle's Half-Sister Samantha Wants Duchess to Take Lie Detector Test: 'I'm Sick of The Bulls**t'

Meghan Markle's half-sister claims the Duchess of Sussex lied in her five-page letter to their father, and now Samantha Markle wants the royal to take a lie detector test.

Thomas Markle released a handwritten letter by Meghan Markle months after her wedding to Prince Harry last year. The contents of the letter were based on Thomas Markle's absence at the royal wedding and the drama he's presented to the press since before the couple tied the knot, starting with his staged paparazzi photos. In response to a People magazine story, in which a few of the duchess's friends refuted Thomas Markle's claims that he had not been in contact with his daughter since her marriage, Thomas Markle released the letter to The Mail on Sunday, calling it a "dagger to the heart."

Samantha Markle also took offense to the letter, in particular to Meghan Markle's comments on the "vicious lies" her father and half-sister have spread about her in the press. Samantha Markle shared her two cents about the letter with British tabloid Daily Star Online on Tuesday.

"If pointing out that she is nothing like [Princess] Diana breaks her heart, too bad it's true. If pointing out that she has been coldhearted to my dad before, during and after heart attacks breaks her heart, too bad it's true. If pointing out the fact that I had said once if she treats her own family like this she will treat the Royals like this, breaks her heart, too bad it's true," Samantha Markle said. "If pointing out the fact that she needs to go to school to learn how to be a true humanitarian and all truest breaks her heart, too bad it's true. If pointing out the fact that that letter was a manipulative lie breaks her heart, too bad it's true."

Samantha Markle seemed to be most disturbed by Meghan Markle's admission that she barely even knows her half-sister. "She says she doesn't know me and she lied and said she was never close to my dad. If pointing out that what she says are all lies breaks your heart, too bad because what I'm saying is the truth," Samantha Markle said."

"I would challenge her to take a lie detector test anywhere on the planet with investigators that are not paid by her to skew the results. Quite frankly I had faith in her on and off to do the right thing by her dad but I'm sick of the bulls**t," she said, adding, "Nobody is trying to get close to her but she's not going to ghost, insults, and destroy this family and skip on her merry way without the truth being revealed."
