Kylie Jenner is finally collaborating with Kourtney Kardashian on a collection for Kylie Cosmetics and PRAISE BE.

Kylie has previously partnered with her other Kardashian sisters, Kim and Khloé, on collections for her beauty brand. The youngest KarJenner sister took to Snapchat to announce Kylie Cosmetics' Kourt Collectionm, which will apparently be dropping soon.

In the first Snap, Kylie showed off three palettes in pale green, blue, and pink with "Kourt" written on the front.

The palettes would be interesting enough on their own, but Kylie also showed off three liquid lip colors in the collection. The lipsticks are a stark contract to the pale pastels of the palette packaging, coming in shades of red, brown, and burnt orange. The lip colors do have metallic pastel lids that correspond to the palettes. Of course, we don't yet know what the palettes look like inside those pretty pastel packages.

Kylie showed off the green-lid lip color in a post on her Instagram grid, and in different lighting, it looks more coral. We need swatches, STAT.

Kourtney also has a Kylie Cosmetics Lip Kit named after her (Kourt K, appropriately), but this is her first personal collection within the line. No word yet on when the Kourt Collection will drop, but it's a safe bet that Kylie and Kourtney will both promote it a lot on Instagram when that info is released.
