Now their ghostwriter, Maya Sloan, is speaking out about what it was like to work with the uber famous teens and she had nothing but good things to say about the girls.
The Jenner sisters didn't do any of the writing, and they've been very upfront about that," she explained in her essay for Cosmopolitan. "But they were very much a part of it. They had strong opinions, and we met in New York, where I was now living, and Skyped throughout the process. They read drafts, gave me notes, and I would revise based on what they wanted."
She also explained that they have a bit of a wall up, but after having her own name plastered all over the internet (when it was revealed that she was the ghostwriter), she explained that she completely understands why they would be a bit guarded.
"Behind that wall, which I eventually did break down, are two real girls. They have all the angst, emotions, and intense love of any teenager. That's what I tried to bring out in the book," she concludes.
