Phenomenal Females

Oprah graces the cover of O, The Oprah Magazine each month, naturally. But after learning that she'd be the cover girl for Newsweek magazine's issue about 20 of the most powerful women in America*, Oprah was inspired to take action.

She called on some of the smartest, coolest women she knows to handpick phenomenal females that viewers need to get to know. Oprah enlisted the help of Diane Sawyer, Alicia Keys and Gayle King to find women who are changing the world. Oprah also had a few picks of her own.
