Kylie Jenner teases fans: Is a makeup line in the works?

We may have another Kardashian-Jenner product on our hands (or well, our lips)! Kylie Jenner teased her fans last night that they can probably expect a new beauty product with her name on it... in the near future.

Wearing a simple ripped tee and dark lipstick, she posted a pouty photo to Instagram with the caption: "Brown lips #KylieLipKit stay tuned." Judging by the dark hue on her lips, we're betting on a fall debut! But the possibilities are endless -- will there be multiple shades? Will it come with a lipliner and a lipstick? What about a gloss? And how about a plumping formula if you really wanted to emulate Kylie's famous pout?

We'll just have to wait and see!
