13. Oprah Winfrey
Arguably one of the most famous unmarried ladies nowadays would have to be the one and only Oprah Winfrey. Everyone knows she has Stedman Graham in her life and has been with him for the last 30 years or more. However, Oprah and Stedman have never walked down the aisle together and that’s not expected to change anytime soon. When asked directly about her getting married, the big O had this to say, “I’m not a traditional woman and I haven’t had a traditional life, and I think that had Stedman and I gotten married, we certainly wouldn’t have stayed married.” An interesting way of looking at it, you have to admit. But with an estimated net worth of $3.1 billion at this point, maybe there’s some financial aspect to it.
