I Know Why the Caged Bird Sings
Winfrey has also had a long friendship with Maria Shriver, after they met in Baltimore. Winfrey considered Maya Angelou, author of "I Know Why the Caged Bird Sings", her mentor and close friend; she called Angelou her "mother-sister-friend". Winfrey hosted a week-long Caribbean cruise for Angelou and 150 guests for Angelou's 70th birthday in 1998, and in 2008, threw her "an extravagant 80th birthday celebration" at Donald Trump's Mar-a-Lago club in Palm Beach, Florida.
