Oprah Winfrey and Stedman Graham
Oprah has always been known by her first name only and adding Stedman’s last name to her stationery over the years hasn’t been a top priority. She’s forever the Queen of Daytime and he remains her steadfast King despite not having the official title. Besides, she’s Oprah. And he’s Mr. Harpo. A lot of us are too set in our ways to change how we address them but they’ve got enough money in between them not to care.
