MEGA Meghan Markle's half-sister, Samantha Markle, is once again taking legal action against the Duchess of Sussex. In the Suits star's explosive 2021 interview with Oprah Winfrey, the actress made disparaging comments about her family being fame-hungry, angering Samantha, who is 17 years her senior. Samantha went on to sue Meghan for defamation, and while her case was dismissed with prejudice, she has the opportunity to make an oral argument in September as part of her attempt to appeal the dismissal.
