Meghan Markle's half-sister said Monday that her estranged sibling suffers from "narcissistic personality disorder" — while Markle's hubby, Prince Harry, is the victim of Stockholm syndrome.

"I definitely see a narcissistic personality disorder. I'm not diagnosing her. She needs to see a counselor,'' Samantha Markle told the Australian radio show "Fifi, Fev and Nick'' the day after Meghan and Harry's bombshell TV interview with Oprah Winfrey.

"I feel sorry for Harry,'' Samantha said. "She pulled him away from his family, all of his friends, the life that he knew.

"He reminds me of one of those kidnap victims who eventually starts to believe that their life was so horrible and they're in love with their captor."

In addition to taking on the royal family during the sit-down with Winfrey, Meghan ripped into Samantha, throwing shade on the half-sister's new "tell-all'' memoir, "The Diary of Princess Pushy's Sister Part 1.''

"I think it would be very hard to tell all when you don't know me," Markle said.

Meghan claimed that the last time she saw Samantha "must have been at least 18, 19 years ago'' and referred to herself as "an only child."


"She had said, 'I haven't hadn't seen Samantha for 19 years.' Well, she was at my graduation from my bachelor degree — there was so many photos in the media that are ... about that, and that was 2008, so don't know about you, but if you do the math, 2008 to now is not 19 years!" Samantha said.

"To suggest that she was an only child was really delusional,'' the sibling added of Meghan.

Samantha also challenged Markle over presenting herself as absolutely clueless about the royals before she met Harry.

Meghan told Winfrey, "I didn't grow up knowing much about the royal family. ... I never looked up my husband online.''

Samantha claimed, "She's been seen in several photos in front of Buckingham Palace!

"She idolized Diana,'' the sibling said, referring to Princess Di, Harry's mother.

"In fact, Meghan went to great lengths to study Diana, to mimic her clothing, to mimic her body language and to wear Diana's perfume on their first date! Don't tell me my sister didn't know who Harry was!"

Meghan claimed Samantha only changed her married name back to Markle after the now-royal began dating Harry — but Samantha said, "First of all, I did an interview, and I held up my college degree — my name's been Markle since 1964 — it's on my college degree!"

Meghan also publicly accused her dad of "betrayal'' by selling her out to the tabloids and lamented to Winfrey, "I've lost my father."

Samantha, who has the same father, Thomas Markle, said their dad watched the interview and "He's very hurt.

"And for her to say, 'I lost my dad,' I felt like, oh, my God, and the Oscar goes to, 'I lost my dad!'

"[Oprah] needs to get Dr. Phil on my sister,'' Samantha said, referring to Winfrey's favorite TV psychologist, Dr. Phil McGraw.
