After working with both Kim and Khloé Kardashian on lipsticks and palettes, Kylie Jenner has now tapped another sister for a kosmetics kollaboration: Kourtney Kardashian.

"So excited to announce the Kourt x Kylie collaboration. This collection gives me so much lifeeeee!" Kylie wrote on Instagram. In her reveal, she said there will be three mini eyeshadow palettes and three lipsticks all launching 24th April. We got the full run-down of what to expect over on Kylie's Instagram stories.

The packaging is holographic.

There's a golden shade literally called Gluten Free.

Kourtney is the Kardashian family's resident health nut (her sisters often tease her about it on Keeping Up). She and her kids are famously all on a gluten and dairy free diet.

The swatches are impressive. The shadows look like they have a strong colour payoff.

The three lipstick shades are inspired by Kourtney's go-tos: pink-nudes and reds.

Both Kylie and Kourtney wear the "Rad" lipstick in promo photos.

Now that Kourtney's done a makeup collection with Kylie, the only one left to join forces with is Kendall. Will she be next?
