Meghan Markle has been sued by her half-sister for allegedly making "false" statements in the interview she and Prince Harry gave to Oprah Winfrey in 2021.

Samantha Markle filed the lawsuit on Thursday in Florida and accuses the Duchess of Sussex of defamation "based on demonstrably false and malicious statements" made by Meghan in the sit-down interview viewed by millions around the world on March 7, 2021.

Samantha, who shares father Thomas Markle with the duchess, claims Meghan's "lies" were "designed to destroy [her] reputation" and have subjected her to "humiliation, shame and hatred on a worldwide scale," the documents obtained by Fox News Digital allege.

Samantha argues that Meghan lied about being an "only child" and about the last time she saw Samantha. She also claims Meghan falsely stated that Samantha changed her last name to Markle after Meghan started dating Prince Harry.
