And we can see how the reality star, who recently married Professor Green, manages to stay so flawless and gorgeous-looking. With plenty of beauty sleep, that's how!
If these "night in" must-haves are anything to go by, Millie was obviously looking forward to going to bed early last night (20 November) – with some of her favourite beauty treats to help her sleep.
Sleep is one of the best things you can do to help keep your good looks, as this is the time when your skin regenerates and repairs itself.
It also puts paid to dull hair and those dreaded eye bags we all get plagued with if we don't get enough shut-eye...
So, what does Millie like to use to help pamper and relax before going to bed.
Well, it looks like she relies on Aromatherapy Associates Inner Strength Bath and Shower Oil, £39, aromatherapyassociates.com which is a beautiful oil that helps to relax, calm and balance the mind and body.
She's also clearly a big fan of This Works Deep Sleep Pillow Spray, £16, this works.com which is infused with essential oils of lavender, vetivert and wild chamomile – in other words, it's the miracle solution to a good night's sleep!
Now 55 quid is not to be sniffed at for a mere 2 beauty products but if they get us even close to waking up looking like Millie, we might just be tempted!
Or they can at least go on our Christmas wish lists, that's for sure...
