Jessica Simpson has admitted to sleeping with ex-husband Nick Lachey before they finalised their highly publicised divorce.
In her candid memoir Open Book, the singer and businesswoman says that she met with Lachey at her house after she witnessed him pour his heart out over their break up in MTV documentary.

“I just wanted to know what he thought of me now, because at that point I had no idea,” she wrote in her book. “I watched him portray himself as a victim, casting me as this selfish person.”
Simpson goes on to admit that she felt the need to “fix him” after watching him break down in front of the world.
“He rang the bell, and out of reflex I hugged him,” she wrote. “I meant it, too. Despite my anger, I missed him.”
“I was numb, just blank. How do you react when you find out you have apparently hurt someone so deeply that they feel entitled to such actions? I felt manipulated into some revenge fantasy, but I had put myself in this situation,” Simpson wrote. “I didn’t know any other way to make it better, so I slept with him.”
Simpson also revealed that she felt absolutely no connection to him.

“He didn’t stay the night. I was relieved because I could feel his hate. The whole situation was very dark,” she added. “When he walked out the door, I knew I would never see him again.”
The admission comes days after she admitted to having an “emotional affair” with Johnny Knoxville.
Writing in the same memoir, Simpson said she formed a bond with the Jackass star while they were filming the 2005 film, Dukes of Hazzard.

“I could share my deepest authentic thoughts with him, and he didn’t roll his eyes at me. He actually liked that I was smart and embraced my vulnerabilities,” the 39-year-old wrote.
“He believed in me and made me feel I could do anything.”
“First off, we were both married, so this wasn’t going to get physical,” she wrote.

“But to me, an emotional affair was worse than a physical one. It’s funny, I know, because I had placed such an emphasis on sex by not having it before marriage. After I actually had sex, I understood that the emotional part was what mattered.”
She added, “Johnny and I had that, which seemed far more of a betrayal to my marriage than sex.”
Simpson and Lachey divorced in 2005 after seven years together and three years of marriage.
