It appears that Meghan has occasionally used “Sussex” as a surname in more casual situations. For instance, during conversations with Mindy Kaling and on The Drew Barrymore Show. When she was on The Drew Barrymore Show on March 6 to discuss her latest projects, host Drew Barrymore introduced her by saying, “This is the Fast Five with Meghan Sussex.”
Why its raising eyebrows
Meghan Markle was publicly addressed as “Meghan Sussex” for the first time, sparking criticism. Many argue her surname should be “Mountbatten-Windsor” since “Sussex” is a title, not a last name.
Royal fans questioned the choice, with some pointing out she wouldn’t use “Meghan Sussex” legally. Her father, Thomas Markle, also expressed disappointment, believing she is distancing herself from the Markle name, which would have saddened his late mother.

Thomas criticized Meghan’s public persona, calling it inauthentic. Their relationship remains strained since he missed her 2018 wedding, with some blaming his media appearances for their ongoing rift.
Meghan’s Name Choice: A Royal Controversy?

There’s no issue with Meghan using “Meghan Sussex” as her name—many royals use their titles as surnames. Prince Harry, for example, went by “Wales” in the army, following royal tradition.
Despite this, the media still refers to her as Meghan Markle, as seen in People magazine. Her choice to adopt “Sussex” has sparked debate—some see it as fitting, while others question the connection.
And then there’s the ever-present Mountbatten-Windsor discussion—royal naming conventions never fail to stir controversy. What’s your take?
