Kylie Jenner鈥榮 cosmetic line has been ultra popular, especially those ubiquitous lip kits. In fact, her launches usually sell out within a matter of hours. Now it looks like Jenner is trying to make her products really #breaktheinternet, because she鈥檚 teaming up with her famous big sis Kim Kardashian West to release a new makeup collab.

COMING SOON @kyliecosmetics #KKW

A video posted to Jenner鈥檚 Insta page teases the launch and features her and her sister getting prepped with nearly identical looks: glossy, pin straight hair, dewy skin, and nude lips. Is that a lip kit we see?

We aren鈥檛 sure yet what the result of this project will be. It could be more lip kits or Kylighters, or maybe something entirely new and different. Fragrances? Cream foundations? Something glittery (the unicorn trend isn鈥檛 dead, after all)? But our guess is a nude lip kit 鈥 because that lip shade is featured most prominently in the teaser.

We also aren鈥檛 sure when the mystery collaboration product(s) will be released, but the video announces: 鈥淜KW X KYLIE COMING SOON,鈥 so we suspect it鈥檒l be within the next few months 鈥 hopefully by summer.

What鈥檚 your favorite beauty product right now? Tell us @BritandCo!
