That's why we were shocked to hear her make a pretty huge beauty confession recently - aside from sleeping in her slap and washing her hair with three different shampoos, that is...
While many of us have been taught by beauty know-it-alls to reach for a primer before buffing in the concealer and working in our foundation, Kimmy gives that part of her make-up routine a miss in favour of a small dollop of moisturiser before applying her base - and the product she adores is the Kiehl's Ultra Facial Cream, £24.
A cult classic constantly being snapped up by the likes of Ella Eyre, Christina Milian, Tinie Tempah and now the Kardashian-Klan, this little pot of magic lends lacklustre skin a new lease of life, all while protecting skin from whatever your day throws at it - be it pollution, bitterly cold weather and yep, your fave foundation.
In fact, it was Kim's make-up artist, AKA beautifying genius Mario Dedivanovic, who advised her not to pop on a slick of primer before glamming up.
At his latest masterclass, Mario told the crowd of beauty obsessives: "I don't use [primers]. I don't like to put barrier between the skin and the makeup," and mentioned that a moisturiser like this one "really helps the foundation to blend" and mesh entirely with the skin for a seamless finish without streaks.
Who'da thought? Now if you'll excuse us, we're off to grab us a few pots...
