Britney Spears has reportedly finished work on her forthcoming memoir. 

The pop superstar has been hard at work on the tell-all tome and, according to sources, she’s set to drop the “inspiring” book this year, describing it as a “groundbreaking instant best-seller.”

“Britney’s book is a story of triumph. It will cover her most vulnerable moments, her childhood – being a little girl with big dreams – her breakup with Justin Timberlake, the moment she shaved her head, and her battle with her family over her conservatorship,” said one source (via Page Six)

“It is also a story of survival, finding her way out of the crippling conservatorship to finding happiness with her husband Sam Ashgari.”

According to the publication, the Toxic star has been working with ghostwriter Sam Lansky, who has written for The Atlantic, New York Magazine, Time and has profiled Madonna, Nicki Minaj and Adele, among others. 

Publisher Simon & Schuster is planning a release ahead of the holidays, with insiders adding: “Britney’s book is brutally honest and from the heart. No stone is left unturned. Its truly a female empowerment story – her taking control of her life.”

A second publishing source added: “This book is a gift….There are parts of this book that every person—particularly every woman—can relate to and feel less alone. She transforms joy and pain into something transcendent: art. 

“This is an inspiring read, not only because it shows the strength of Britney’s spirit, but because her story is told with such style, wit, intelligence, honesty, and without any self-pity. She is entirely winning in these pages.

“This book will… shake the world. I believe that it will also be a groundbreaking instant bestseller.”
