Finally, the makeup collaboration we didn't know we've been waiting for is here! On April 13, Kylie Jenner announced a Kylie Cosmetics collaboration with her sister Kourtney Kardashian called (what else?) "Kourt." Five days later on Kourtney's birthday, we finally have a full list of products, a release date, and Kourtney's explanation on how it came to be. Watch the video above to see the stunning products from the Kylie and Kourtney collaboration.

"KOURT X KYLIE 4/24," wrote Kourt on April 18. "I am so excited to announce my collaboration with @kyliejenner ? We have been working on this for a year… 3 mini eyeshadow palettes and 3 lips… I am wearing Matcha on my eyes and RAD on my lips. Happy Birthday to me!" Kylie wrote, "HAPPY BIRTHDAY TO THE QUEEN! ? so excited to announce the KOURT X KYLIE collaboration. This collection gives me so much lifeeeee! 3 mini palettes & 3 of Kourtney’s signature lippies launching 4/24! Collaborating with you was so much fun! I love you!"

This collaboration seems like a long time coming, because Kourtney was the last of the three Kardashian sisters to get a line with Kylie Cosmetics. First there was the KoKo collab, then came KKW x Kylie Cosmetics launch. However, this one will probably be special in that Kourtney doesn't wear a ton of makeup and tends to go more for subdued looks. Judging by the videos, the colors look chic and toned-down, so us career gals can have the perfect work-day glam. Now we just need Kendall Jenner to collaborate and we've got a full KarJenner collection!

We were so excited about the new makeup that for a second we forgot about Khloé's recent birth and cheating scandal… which is probably why Kylie announced it now in the first place. The news comes just one day after Khloé welcomed her first child — a little girl — with boyfriend Tristan Thompson. And that news came just one day after videos and photos surfaced of Tristan cheating on Khloé with several different women. Yeah, it's a dramatic time or the Kardashian Klan.

Kylie didn't rush to the hospital in Cleveland with the rest of the family, but she seems to be doing everything she can to support her big sis. She started by posting a million selfies (seemingly to distract the public from what was going on) and then she took to Snapchat to congratulate her sister on the happy news. Now she's back to hogging the spotlight, but we bet Khloé doesn't mind.
