Oprah Winfrey
To call Oprah Winfrey, a public figure is an understatement. This international renown, multi-talented woman is a talk show host, producer, actress, television producer, and philanthropist. Her various successes in business earned her the record of the first black woman billionaire. Over the last 30 years, Oprah had been in a relationship with Stedman Graham for about three decades. However, the duo remained unmarried. There are speculations that the celebrity chose not to tie the knot to avoid a “high-profile” and expensive divorce.
