The "Keeping Up With the Kardashians" star shined as she posed for pictures with photographer Brian Bowen Smith at his "Metallic Life" gallery event in West Hollywood, Calif. on Thursday night.
Sporting black leather pants with a sheer black tank with lace embroidery, the mother-of-three showed off her super slim post-baby bod.
The 36-year-old beauty was one of the celebs who stripped down for the Vanity Fair photo spread, where she put her naked booty on full display as she laid on her side. Each photograph was printed on metallic paper, accentuating the "tantalizing textures of skin," Smith told the mag.
To prepare for the racy shoot, Kourt spent a lot of time in the gym. She recently shared a workout selfie on Instagram, where she flaunted her super-fit physique in a black sports bra, leggings and Nike sneakers.
"Working out is one of the only things that helps when I'm feeling anxious," she captioned the sweaty snap.
