Jessica Simpson is currently writing a memoir which will include all of the juicy details of her marriage to former boy band member, Nick Lachey.

"I will be releasing my first book on February 4th with @harpercollinsus," she on Instagram. "I have been working so hard on it – I have opened my heart up in a way I never have before and now I can't wait to share it with the world."

The former pop star did not reveal much about what will be in the book, but the book's description reveals that she will be spilling the tea about her highly publicized marriage and divorce to Lachey:

"From her popular television show 'Newlyweds,' to a very public divorce, starring on the big screen and topping the Billboard charts, finding new love, raising a family, and running a successful business empire, her new book will be a candid, inspiring, and behind-the-scenes look at how she chose to learn from each difficult moment, evolve musically, become a more fearless businesswoman, and consistently shatter all expectations of who she was 'supposed' to be."

Jess was married to Lachey from 2002 to 2006 and even landed their own reality television show on MTV.
