There's Koko K - a soft pale pink for Khloe Kardashian, Kourt K - a dark purple plum for Kourtney Kardashian, and Mary Jo K - a red with orange understones (how jealous do you think Kim is right now?).
But it turns out Kourtney isn't the biggest fan of her namesake matte lipstick. Shocker!
In a new interview with Cosmopolitan, Kourtney revealed that she actually prefers Kylie's lip glosses.
When the mag asked her what her favourite Kylie Cosmetics lip shade was, she answered: "I love the lip gloss called Literally."
Kylie appeared totally unfazed by the comments, taking to Instagram to promote her latest Lip Kit shade Dead Of Knight - a pure matte black - with what could be her most sultry snap yet.
We reckon the rest of the Kardashian clan are waiting with bated breath to see who she names one after next. But we have a feeling it's still not going to be Kim (sorry Kim).
