Meghan Markle’s half-sister Samantha Markle just attacked the Duchess of Sussex because of her Christmas card with Prince Harry.

On her Twitter account, Samantha dubbed the royal couple’s Christmas card as “incredibly rude.” The book author also seconded some critics’ comments and questioned why the couple has their backs turned toward the camera in the card.

“Is this towards the world or just the Ragland and Markle family? It’s a bit sad; face the Christmas spirit,” she wrote.

Samantha went on to say that it is incredibly rude to turn their back in a Christmas photo because the card is meant to share warmth and good wishes with the world. She also defended herself from critics that might question why she’s pointing out the truth.

But some royal fans shared the same comments about Prince Harry and Markle’s Christmas card. After Kensington Palace released it on Friday, some of them said that they were not happy to not see the couple’s faces on the card. One fan said that the snap looks very much like Hollywood since Markle used to be an actress.

Meanwhile, this is not the first time that Samantha slammed her estranged half-sister on social media. She previously accused the Duchess of Sussex of being cold after she ignored their father. Samantha also branded Prince Harry as a wuss and said that she would blame her half-sister if their dad, Thomas Markle Sr., died.

As of late, the “Suits” alum has not yet spoken to her dad and half-sister. They have not been on speaking terms since before Prince Harry and Markle tied the knot on May 19. Prior to their wedding, the Duke and Duchess of Sussex invited Thomas to attend their nuptials at St. George’s Chapel in Windsor Castle.

However, he was unable to make it to the venue because he suffered a heart attack weeks earlier. And in the days leading up to the royal event, the former lighting director underwent heart surgery. Prince Charles was the one that walked Markle down the aisle instead of her own father.
