Luminous! Kim Kardashian, who's pregnant and expecting her second child (a boy!) with Kanye West, is the cover star of the August 2015 issue of Vogue Spain, and the reality star looks positively radiant without a stitch of makeup.

The social media maven, 34, gave fans a sneak peek at the spread via her Instagram page on Friday, July 17. "Vogue Spain Cover! We did this whole shoot without make up! Can't wait for you to see it!" she wrote, tagging the photographer, Theo Wenner, in thanks.

Indeed, in the cover shot, Kardashian appears makeup-free (save for moisturizer and a touch of lip balm) and fresh-faced—no contouring, no mile-long lashes, nothing but her natural pregnancy glow. There's no glam dress, either, just a cable knit sweater that she's bundled up in. The only pop of glitter comes from her massive engagement ring, which sits on her left hand, propped up right in the middle of the image.

Thank You!

The inside spread is just as relaxed. In the one early image shared on Vogue Spain's website, Kardashian can be seen lying down on an emerald couch with her jeans unzipped and her legs curled up, a pose that puts her famous derriere on display.

As Kardashian's makeup artist Mario Dedivanovic told the fashion mag, "This was the only time it literally took us a minute to prepare her face for a photo shoot!" But he added, "She spends most of the day at home with her daughter [North] without a drop of makeup, so she's used to it. [Her face] is just as amazing without makeup because Kim is glamorous."
