The reality TV star has been busy soaking up the sun, wearing some jealousy-inducing outfits and, best of all, partying it up with her husband Professor Green.
On Sunday (27 April) Millie started her day in the best possible way… With a mimosa at super glam Italian restaurant Cecconi's in Hollywood.
She said: "Sunday brunch #mimosas #isthisabadidea #pastaforbreakfast."
This tasty little treat was followed swiftly by what looks very much like a bloody mary to us.
Millie added: "Sunday session @professorgreen you are trouble."
By Monday morning, Mills was obviously feeling like it was time for a bit of a cleanse.
She shared a snap on Instagram of her new beauty secret – sachets of Skinade.
Millie said: "This little sachet of @skinade travel has been my LA beauty secret. My top tip for flawless skin."
Skinade sachets contain nutrients, vitamins and collagen and are said to help hydrate the skin from within.
And while £33 for 10 sachets isn't exactly the cheapest, Mill's is a former Made In Chelsea star so she probs didn't bat an eyelid!
