The 'I Can' musician will collaborate with Rolling Stone writer Touré to tell his life story in It Ain't Hard to Tell.
Touré tweeted that he's excited to be working on Nas's book, writing: "I've been talking to Nas about writing his autobiography for 15 years. This is hiphop history. We'll tell his life & deconstruct some songs."
Nas will reportedly open up about his four-year marriage to Kelis and his public feuds with Jay-Z and Bill O'Reilly.
It Ain't Hard to Tell will be released by Atria Books in fall 2012.
Kelis insisted earlier this year that she has no regrets about divorcing Nas.
Nas has said that his upcoming studio LP Life is Good is spiritually uplifting.
