It's such an amazing feeling, the transformation that your body goes through. There's something about that that's so empowering and beautiful and I just really embrace it."

Moments before she went into labor, the 35-year-old reality TV star even managed to share an Instagram post of a picture of a baby doll lying in the brand new crib she just got for her expected child according to US Weekly.
