Kim Kardashian and Kylie Jenner both have their own beauty lines, but fans of the KKW Beauty and Kylie Cosmetics owners may take delight in the news that a collaboration may be underway.

While the members of reality clan have taken their own ventures, Kardashian and Jenner both have released their own makeup lines, KKW Beauty and Kylie Cosmetics, respectively. Many people might be wondering if there's a competition between the two makeup mavens, though the latest news that a collaboration between the two is enough to smash the malicious rumors.

While there is still no official word whether the collaboration is to happen, which will be the second time for KKW Beauty and Kylie Cosmetics, if it will materialize, the mom of Stormi dropped a major hint that may have let the cat out of the bag. Jenner's throwback photo on Instagram she shared just days ago may have hinted of what's good to come from a team-up between her and Kardashian.

"[T]hrowback who wants KKW X KYLIE round 2?" Jenner captioned the photo of her and her half-sister in a photoshoot, presumably during the initial collaboration.

Of course, the news should be taken with a grain of salt. Nobody really knows what's going on in Jenner's head. It may be that she's just reminiscing on the successful collaboration or that the post is just a major inkling on the upcoming project of her and Kardashian.

As mentioned, this wouldn't be the first time KKW Beauty and Kylie Cosmetics will collaborate. The first one happened even before Kardashian's makeup line was launched. The first team-up resulted to four crème liquid lipsticks. These beauty products are available in chic nude colors Kim, Kiki, Kimberly, and Kimmie. These items that come in set remain available in KKW Beauty's website.

For the second collaboration, if there would be one, it is still unclear which beauty product they're going to produce. After all, both KKW Beauty and Kylie Cosmetics have expanded their respective lines, and that means they could just leave out lipsticks for this time since they already did that in the first run.

Collaborations In The Family

Meanwhile, collaborations aren't exactly a new concept to the Kardashian-Jenner clan, a family that's been known to have close ties yet have raucous tirades against one another at times. Kylie Cosmetics lately had a team-up with the family's matriarch, Kris.

That's not all, Kylie Cosmetics had also collaborated with Khloe Kardashian in bringing the Koko Collection. Makeups from this collection came in a shiny rose gold packaging that spells "extra" all the way.
