The 25-year-old will unveil illustrated memoir My Crazy Beautiful Life on November 20, reports The AP.
She said that while not every part of her life is "glamorous", the story she has to tell is all true.
Ke$ha said: "Sometimes, it feels as if the last few years have encompassed a few decades. You might have heard my voice on the radio, seen me on stage and on the red carpet, or in a music video, but that's only a part of the story.
"In these pages, I'm revealing a more complete picture of what my life is really like. It's not all glamorous and it's not all pretty, but it's all real."
She added: "In less than three years I've gone from being the worst waitress in LA to living out my childhood dreams of singing my songs to people all over the world."
The singer, who was born in Los Angeles and brought up in Nashville, releases her second album Warrior in December.
