At age 80, Willie Nelson is ready to say it all.

Little, Brown and Company announced Wednesday that the country music superstar has a book deal with the publisher. Although Nelson is the author of several books, Little, Brown promises that this one will be an unvarnished story about the artist known for "Blue Eyes Crying in the Rain," "Funny How Time Slips Away" and other classics.

The memoir is untitled. It is scheduled to be published in 2015.

Nelson's previous books include an autobiography published in 1988 and "Roll Me Up and Smoke Me When I Die: Musings from the Road."
