When every moment is constantly being filmed, it’s hard to relax.

I would say a lack of sleep is a cause for feeling not so beautiful. On those days, I try to drink lots of water and put on the biggest sunglasses I can find.

Fashion is so subjective, and I think it should be playful.

Ive been wearing lipstick since I was in 7th grade. That was our form of daring self-expression, because we had to wear uniforms in school. It made our teachers so angry.

My stepdad is Bruce Jenner, the Olympian. The first time he came over was like a blind date, and we had show and tell. He took out the gold medal for me and my sisters, and we were like, 'So? Who the hell are you?'

I remember one day I was kissing Mason and he spit up in my mouth and I loved it.

Motherhood has most definitely changed me and my life. Its so crazy how drastic even the small details change - in such an amazing way. Even silly things, like the fact that all of my pictures on my cell phone used to be of me at photo shoots - conceited, I know! - but now every single picture on my phone is of Mason.
