Keith Richards is writing a children's book. He really is.

The Rolling Stone who came to define the adults-only lifestyle of rock has a deal with Little, Brown Books for Young Readers for a picture story called "Gus & Me: The Story of My Granddad and My First Guitar."

The publisher announced Tuesday that the book will come out this fall and will include illustrations by Richards' daughter, Theodora Richards. Barnaby Harris and Bill Shapiro are assisting with the writing.

"Gus" is Gus Dupree, Keith Richards' beloved musician-grandfather. In a statement issued by the publisher, Richards said the book was based on "one of those magical moments" he had with Dupree. Richards, 70, has five grandchildren of his own. His memoir "Life" was a million seller published in 2010.
