Ke$ha has written a book all about her life!
The book is called My Crazy Beautiful Life and it's a book about what Ke$ha has done in her 25 years of living.
James Van Der Beek shared her story as she said:
"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. 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 onstage 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."
The book comes out on November 20th!
