Kim & Kylie Kardashian have even both managed to have booming beauty brands without competing with each other much, as they are both doing different things within the industry. KKW Beauty has so far been more about base makeup, like contour & highlight, while Kylie's brand is more about lips & eyes. 

But, Kim's recent Instagram has some folks wondering if she is developing a product that will bring her into new territory.

The photo is of a simple lip print on a napkin, but the fact that Kim has tagged KKW Beauty in the photo is raising some questions. People normally tag the brand they are using in photos like this, but KKW Beauty does not at present have any lipsticks (or other lip products) for sale. Does this mean that they are now developing something?

We will have to wait & see, as it seems like a KKW Beauty concealer may be on the way first. While it's totally comprehensible for Kim to want to have a focused beauty line, it would also be great to see what a KKW Beauty lipstick would be like.
