2. Oprah Winfrey

Oprah Winfrey was a huge fan of the book I Know Why the Caged Bird Sings written by a poet and writer, Maya Angelou. The 2 first met in the ’70s at the beginning of Oprah’s career. And since then, Angelou became Oprah’s precious mentor and even more than that. “She calls me her darling girl, and I call her my mother-sister-friend. She was there for me always, guiding me through some of the most important years of my life.”
