London, Aug 17 - American actress-singer Jessica Simpson is planning to write a tell-all book.

The inspiration for the book is her break-up with recent boyfriend Tony Romo, who dumped her on the eve of her 29th birthday July 10, reported aceshowbiz.com.

'Being dumped by Tony was the final straw. That's what made her decide to write a book and reveal everything she has gone through in the name of love,' said a source.

'Jessica has been through so much pain and heartbreak with the men in her life and often thought about writing it. Her book might cover everything about the men who have crossed her path,' added the source.

The planned tell-all book will include Jessica's relationship with ex-husband Nick Lachey as well as then-boyfriend John Mayer. She will also write about her battle with weight throughout her career.

No possible title and release date for the book have been announced.
