Meghan Markle's half-sister, Samantha Markle, didn't like Chrissy Teigen's comment about their dad.

On Sunday, Samantha took to Twitter to criticize John Legend's wife for commenting on her dad and sister's issue. According to Samantha, the "Lip Sync Battle" co-host knows nothing about their family affair. "So this pudgy airhead @Christinetiegen Who knows nobody in the family is opening her pie hole? 'This guy' is our father and deserves a lot of respect,.. you are the one who sucks," Samantha wrote.

Despite Samantha's rant, some of her followers supported Teigen. One user said that Samantha and Thomas' actions deserve a response from the public.

"The things your family, including your father, has said about Megan and the Royal family are fair for a response from the public. Judge and you in return are judged especially if it's in a social network. End of story," Brenda Scott commented.

Meanwhile, another follower caught Samantha's attention for spelling Teigen's last name wrong. According to Brandie King, Markle's sister did it on purpose because she really had no intention to tag the model as she was not ready for the backlash.

Markle and Samantha's father, Thomas, made another interview recently and spoke about the Duchess of Sussex and the royals. In one of his statements, he mentioned the late Princess of Wales. According to Thomas, Princess Diana would surely loathe the way the royals instructed Markle to treat her own father.

In response to this, Teigen took to Twitter and criticized Thomas. "this guy...this guy sucks. what is wrong with him? let your daughter be happy, please. this is embarrassing," Teigen wrote.

Samantha has always been backing their dad. In fact, she said that she was to blame for Thomas' staged photos in the run-up of Prince Harry and Markle's royal wedding.

"The bad press over my father doing staged photos is my fault. The media was unfairly making him look bad so I suggested he do positive photos for his benefit and the benefit of the royal family. We had no idea he would be taken advantage of. It was not for money @KensingtonRoyal," Samantha wrote.
