Meghan Markle has revealed that her last name is Sussex (as opposed to Markle, thank you), and it's not that complicated.
Drew Barrymore addressed Meghan Markle as “Meghan Sussex” after the royal corrected Mindy Kaling for calling her by her maiden name in her Netflix series, With Love, Meghan.
Before Prince William and Prince Harry got married to Kate Middleton and Meghan Markle, respectively, the brothers used a surname that honored their father King Charles III's former royal title.
