Jenner explained that she and Bissinger were going to work hard to make sure her story was "told with a lot of honesty and care."
Recently, Jenner sat down with ET for an exclusive interview, in which she opened up about the moment she realized her youngest daughters, Kendall and Kylie Jenner, knew things were "going to be OK" after Jenner came out as transgender during her 20/20 interview with Diane Sawyer in April 2015.
"[Supporters] were all just going crazy on social media,” she recounted, referring to the slew of celebs who took to Twitter and Instagram to share their love with Jenner after the interview.
"I think at that point it made my two little girls, who obviously live in that world -- I think it made them feel really good," she continued. "Like, 'You know what? It's going to be OK. People still love my daddy.'" Check out the video below to hear more.
