Nick Lachey is opening up about his ex-wife Jessica Simpson’s memoir more than a year after it was released.

Lachey revealed that he had never read the memoir titled “Open Book.”

And he has no plans to ever read it.

However, he has some thoughts about the veracity of the things written in the book.

Lachey said “I knew the book was coming out, but I lived the book. I know what the truth is, so I don’t need to read someone’s version of it in a story.”

Lachey isn’t also worried that Simpson’s memoir will be developed into a small screen project.

Lachey and Simpson were married for four years from 2002 to 2006

However, the pair ended things in a messy divorce battle.

Simpson detailed their tulmutuous relationship in her tell-all memoir.
