Oprah Winfrey & Stedman Graham

This pair truly separates themselves from the rest of the pack when it comes to an odd couple; especially given the fact they’re technically not married. In fact, according to Today, they consider themselves in a “spiritual partnership,” despite Graham popping the question to her back in 1993.

In the interview with Today, Oprah stated they both knew a marriage wouldn’t survive the “day-in-day-out commitment required to make a marriage work. My life with the show was my priority, and we both knew it.” Graham is also busy, with multiple books over his career and other projects.
