For Harper's Bazaar's August 2021 issue, Gigi shared that she kept multiple journals throughout her pregnancy journey. "During my pregnancy, I had one journal that I called my good journal and one journal that I called my bad journal. They weren't that literal, but one was more for the memories, for Khai," she explained. "Maybe one day I'll give her the bad journal just to be real about it."

" "I didn't want to feel guilty about feeling those things or writing those things down. I just liked the separation," said Hadid at the time. "I also have sketch pads where I'll watercolor-sketch, and sometimes I end up writing there too. I write on the back of receipts and keep those in a notebook. I'm not particular about it, and my journals are everywhere around the house. I just pick up whichever one is closest to me and write."
