Meghan Markle’s half-sister Samantha Markle recently dubbed the Duchess of Sussex a narcissist.

On Sunday, Thomas Markle Sr. released a copy of his daughter’s handwritten letter to Daily Mail. In the letter, Markle revealed how she urged her dad to stop reading the tabloids, but he never did. She also accused Samantha of manufacturing lies about her. Prince Harry’s wife also said that she barely knew Thomas’ other daughter.

Hours later, Samantha threw shade at Markle via her private Twitter account. She wrote, “Some narcissists (sic) we’re ‘only children,’ others… wish they were.”

One of Markle’s supporters slammed Samantha and said that it is not Meghan’s responsibility to keep her half-sister in the lifestyle that she thinks she should have.

But one of Samantha’s supporters said that if only the multiple sclerosis patient was black, Markle might care about her. Samantha then replied to the comment saying that if she had $600 million, Meghan would care about her.

Meanwhile, one person slammed Samantha for changing her surname to Markle and accused her of cashing in on her sister’s fame.

“Actually, my name was Markle from birth. My last name Markle is on my degrees and Grant was only a pen name to protect my address. Markle is my maiden name… I had it since 1964,” she tweeted.

The Twitter user went on to say that Samantha just stopped using her pen name after Markle became a royal. The author reiterated that her name was never legally known as Grant.

In related news, Samantha also made headlines two weeks ago when she announced the release dates of her books. “In the Shadows of the Duchess I” is scheduled for release between April and May.” The second part of the book will be released sometime in July.

While speaking with Daily Star, Samantha said that she did not hold back in her books. She also said that people will know a lot of new things if they read her work.
