Shhh: Kendall and Kylie Jenner Are Working on a Secret Fashion Project

Since the Jenner sisters have so much free time on their hands, it seems they've taken it upon themselves to embark upon a new, top-secret fashion project together. The suspense!

Kendall and Kylie have set up a mysterious website, Kendall-Kylie.com, where they invite fans and all interested parties to sign up for a VIP "door list," a privilege which will earn participants front-of-line access to the sisters' elusive new project, whatever it might be.

"We can't wait to show you what's up our sleeve," the new site tells members who sign up for the VIP email list. "Members get secrets before anyone else. As one of the first to secure a spot on the list, you'll be notified the moment new Kendall + Kylie items are available—only here. This is the list, and you're on it. Hope you like surprises."

So why do we suspect it's a fashion project? Because on the sisters' joint Instagram account, there are new shots of them studying fashion illustrations and creating mood boards, seemingly hard at work on something design-related. And since they've worked together many times on fashion lines for brands like PacSun and Topshop, it would be no real surprise to see them do another clothing or accessories project together.
