Meghan Markle's half-sister has slammed her once again.

Markle's half-sister, Samantha Markle, recently attacked the duchess again by questioning her humanitarian efforts. According to Samantha, the Duchess of Sussex should not claim that she's a humanitarian because, for her, she hasn't seen "anything so cold in my life."

"Humanitarians work towards resolve and peace," Markle's sister said (via Daily Express). "But my sister disposed of the entire family. There is no way to candy coat something so foul. What would Gandhi, Mother Teresa or the Pope say about that?"

Samantha went on to insist that Markle's fashion, no matter how similar it is to Princess Diana, doesn't make her similar to the late Princess of Wales. "Copying Diana's fashion savvy does not make her like Diana," she added.

Markle's half-sister previously denied reports claiming that the new royal is planning to meet and reconcile with their dad during her trip to the U.S. Samantha said she spoke with their dad, and no one from the palace has reached out to him for a meeting.

"I speak to him every day and it’s sad but, no, they have not contacted him. There is no meeting planned, that is PR spin. The PR machines can stop trying to make out she’s making an effort. She is not," she told The Sun.

Samantha didn't hide her displeasure with Markle, especially after the former "Suits" actress snubbed their entire family before her royal wedding. She even slammed Prince Harry for allowing his wife to do so.

"It's time to 'man up' @HRHHenryWindsor," Grant wrote on Twitter. "Shout outs about humanitarianism, don't work when you are allowing Meg to ignore the Markles. It is s contradiction. Someone must point out that the 'Emperor is not wearing any clothes'."

In another post in July, Samantha also called Prince Harry coward. She also insisted that Princess Diana would be ashamed of what her son did.

"Harry is a 'wuss' to allow the Duchess of Nonsense to mistreat everyone who has been close to her, especially her family. Diana would be ashamed. Stop wearing Meg's skivvies and bra and take your pants off of her!" Samantha wrote on Twitter.
