The wait to get pregnant was not easy: Kim Kardashian

"(Motherhood) really changes you. When I found out I was pregnant (with North), I was going through an awful divorce, Kanye and I had just been dating for seven months granted, we knew each other for a decade and I was like, 'I can't do this. It's not the right time.' But then I figured, If I'm in my thirties and I'm not ready, I'll never be ready. So it's been the biggest lesson, and the biggest joy of my life."
