The former Made In Chelsea star is always high on our 'make-up bags we'd love to steal' list, so it's hardly surprising we're pretty keen to get our mitts on her latest lippy find.
Taking a quick car selfie earlier today (22 September), Mills showcased her stunning natural beauty by keeping most of her make-up simple.
The starlet flaunted flawless skin along with groomed brows, wearing nothing but a slick of mascara on her lashes.
And her minimal eye make-up was a perfect choice as it allowed her new lip shade to steal all the attention!
Mills opted for a pretty rosy pink hue with a matte finish, which suited her sunkissed complexion and caramel brown locks down to a T.
As for the lippy in question? It's a new one from world-renowned make-up artist Charlotte Tilbury, called Matte Revolution Lipstick in Amazing Grace, £23.
Charlotte recently launched this new line of lippies into her make-up collection - which is sold in Selfridges - and each shade boasts a matte formula filled with ingredients to soften and hydrate lips, along with pigments that help create the appearance of a fuller pout.
Make-up artist Charlotte has worked with the likes of Victoria Beckham, Kate Moss and Cara Delevingne, and lucky Millie is BFFs with her too!
Speaking to Reveal about Charlotte at the Cosmopolitan #FashFest last week (18 September), Millie gushed: "She's amazing, I've loved her since I was like 10!"
We wish Charlotte was our bestie... jealous!
