The feud between the Markle sisters continues. Duchess Meghan Markle and her estranged half-sister Samantha Markle have been at odds ever since Meghan’s royal wedding to Prince Harry last May. After Meghan’s wedding, she had a falling out with their father, Thomas Markle, and Samantha has made it clear that she is on their dad’s side. Now, the 54-year-old slammed her 37-year-old sister in the new documentary Meghan & The Markles: A Family at War.

The documentary aired on the U.K.’s Channel 5 on Friday, March 1, and Samantha shared her thoughts on her little sister after Meghan wrote a letter to their father. In the note, the Duchess of Sussex told Thomas, 74, that he broke her heart “into a million pieces” after he admitted that he was involved in a staged paparazzi photo scandal just before Meghan was set to walk down the aisle. Meghan said she was also hurt by Thomas’ media interviews where he slammed Meghan, her husband, and the royal family.

“She doesn’t have a heart or she would [have] been doing everything she could to make him comfortable, and reciprocate, and be loving and gracious, and make sure he’s comfortable in his old age,” Samantha said during the documentary. “So broken heart? No, his heart’s broken. She can’t turn herself into the victim here.”

In the letter, Meghan allegedly wrote that she “barely knows” her half-sister, but Samantha has maintained that the Markle family was close growing up.

“There are a lifespan of pictures and experiences together, so maybe it’s convenient for her, that in her mind, she doesn’t know us because she doesn’t want to because she wants [to take] center stage,” Samantha continued. “I wasn’t maliciously lying. I was pointing out what the world was already seeing. I pointed out that humanitarians don’t treat their father coldly. Was that a lie? No, because the world watched it happen to my dad, and the world watched her do it.”
