She's happily engaged with a gorgeous little girl and another baby on the way but Jessica Simpson's world could be rocked by the news that her fiance Eric Johnson's ex is reportedly planning to pen a tell-all book detailing how Jess started dating her husband whilst they were still legally married.

Keri Johnson, the ex-wife of former NFL player Eric has apparently already started work on her book, and according to Celebuzz it will chronicle the period when Eric starting dating Jessica while he was still married.

Shes always thought about writing a book through their divorce, a source said of Keri. She actually started writing during the divorce to cope with what was happening.

She just wants to be honest. Keri wants to detail the divorce from her own perspective and what happened, and inevitably Jessica would be a part of that, added the source.

She would talk about how they were so public with their relationship during her divorce.

Eric and Keri were married for five years before separating in October 2009 and filing for divorce in January 2010, just months later Eric started dating Jess with the two spotted at the singer's brithday celebrations in July of that year.

Eric and Jessica announced their engagement in November 2010 before Jess gave birth to their daughter Maxwell Drew in In May 2012, seven months later, she announced she was expecting the couples second child.

Whilst Jess will reportedly be a part of Keri's book, she won't be the main focus according to the source:

Of course she was very upset, but Keris not going to make Jessica the focus of the book,

She wants it to have a greater purpose ! and thinks she can share an interesting story. She wants the book to provide insight into how to cope with divorce and make life transitions.

And it sounds like the story might not even hit the shelves, perhaps Jess doesn't need to worry quite yet:

Shes always struggled with going public. So shes still 50-50 about writing it.
