The talk show star has revealed why she never married her boyfriend in a special issue of O Magazine

The billionaire's magazine, O, is celebrating its tenth anniversary this May. In the interview, the 56-year-old television host has revealed the reasons for not marrying Stedman Graham and not having kids.
