Today’s the day! Kylie Jenner’s latest collab for Kylie Cosmetics will be launching with her big sister, Kourtney Kardashian. After a year in the making, Kylie and Kourtney got everything right and they’re ready to share their collection with the world.

Kylie announced the exciting news via Instagram in a sweet birthday message to her sister Kourtney, who turned 39 last week.¬†“This collection gives me so much lifeeeee!,” Kylie captioned the photo. Ky also revealed that the newest drop will feature 3 mini palates and 3 of Kourt’s signature lip choices.

This has to be one of Kylie’s best drops for her cosmetic line! She’s now teamed up with all of her sisters except for Ms. Kendall, so I wonder when and if that’ll ever happen..!? I would LOVE to see what the two Jenner girls come up with.
