Kourtney Kardashian

My entire life changed when I became a mother - my priorities, my understanding, appreciation of life, and my relationship with God.

I think I forget every time - you give birth, and you want your stomach to be flat again. It does take a lot of work, but I usually start slowly by going on walks with the baby.

I used to play Donna Karan. I used my dad's home office, and Kim was my assistant. Then one of our friends would play a buyer, and I would take her to my mom's closet and show her the new collection.

One Moment in Time because I think it describes me as a person and how I felt about being on the show.

I'd date someone younger or older; age doesn't matter to me. Or looks, really - it's all about maturity.
