The book is due to come out on October 11 and is expected to go into detail about her marriage and split from her soccer player ex-husband Ashley Cole.
The book will cover her childhood and her rise to fame through ITV talent show `Popstars: The Rivals`.
It could also cover her brief stint as a judge on `The X Factor` US - and her subsequent firing by Simon Cowell.
Simon spoke heavily about the 29-year-old singer in his biography by Tom Bower.
HarperCollins said: "For the first time Cheryl will tell her story in full in her own words."
Publisher Carole Tonkinson added: "Cheryl Cole is the nation`s sweetheart. We are absolutely thrilled to be publishing her story.
"Cheryl`s an amazing woman with a capacity to inspire everyone. She emerges from every challenge stronger and with more grace and good humour and beauty - inner and outer."
She continued: "We`re still pinching ourselves that Cheryl chose us as her publisher and we`re going to do everything in our power to make this the Christmas number one."
Cheryl has previously said she would consider writing a book about her life because there are so many unauthorised versions.
She admitted: "I see these girls that say, `This is literally like a bible for me - I read it and I hang off every word it says`, and I`ve had nothing to do with it. I don`t have the heart to say `this book is almost completely made up`."
