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.
