Britney Spears is reportedly set to release a tell-all memoir.

According to Variety, a source said the singer had “landed a record-breaking publishing deal” with Simon & Schuster.

The book will go into detail about Spears’ rise to fame, her music career, as well as her relationship with her family and that much-talked about conservatorship, no doubt.
