So on Monday morning, Millie made herself a packed lunch full of healthy food to take with her on a busy day.
Millie cooked up some broccoli and chicken which she popped in a box, before grabbing a healthy juice and a bottle of water.
Now that's what we call a decent diet on the go! Millie said: "Prepared! Happy Monday everyone."
The former Made In Chelsea star, who married new husband Professor Green last September, had spent her weekend hanging out with Pro.
Real name Stephen Manderson, Millie posted a cute picture of him on Instagram.
The pair also went out to walk their dogs, but got stuck in a rainstorm which meant Millie could make full use of her coat with an enormous hood.
