Oprah Winfrey's company will publish its first book, a part autobiography on Alicia Keys.
The singer's book is titled More Myself.
Keys released her debut album, Songs in A Minor, in 2001 when she was 20.
She has since gone on to record another five albums and win 15 Grammys.
She also co-founded the Aids charity, Keep a Child Alive.
In announcing the partnership, Oprah said on Twitter that Keys has navigated the spotlight and pressures of fame while retaining a humble and beautiful spirit.
