The new season of The Rachel Zoe Project on Bravo TV will be all about her pregnancy. Jezebel summed it up well:
The new season will focus on Rachel's struggle to keep her ultra-stressful life and business in order, all while nursing the bun in her oven. Phrases like "I keep forgetting that I'm pregnant!" during a photoshoot and Rodger saying, "Don't kill my baby!" as a hairstylist sprays an unknown substance onto his wife's head can give you an idea of what this season will be like.
