Because Jessica found Nick's suggestion for a prenup to be offensive, the couple did not go through with any sort of financial agreement before they tied the knot. It wasn't until they were in the midst of their divorce that Jessica wished she would have signed a prenup with her soon-to-be ex-husband. 

At the time of their split, People reported that Jessica was worth an estimated $35 million, while Nick was worth around $5 million, which would explain Jessica's regret.

When it comes to the actual details of the divorce settlement Jessica gets coy in her memoir. "They said Nick wanted a certain number, and honestly I don't remember what it was," she explained, adding that she eventually told them to "just give it to him."

"I'll make it back," she continued. "And then I did. Give or take a billion."
