While the Queen of Talk
-- who has been in a relationship with Stedman Graham since 1986 -- has never had children of her own, she tells the April issue of Good Housekeeping U.K.
that she feels very maternal towards the women in her Oprah Winfrey Leadership Academy for Girls
. "I have 172 girls, and 20 are in college in the United States and use my home as their home base. It is more rewarding than I would ever have imagined," she gushes. "When people were pressuring me to get married and have children, I knew I was not going to be a person that ever regretted not having them, because I feel like I am a mother to the world’s children."
