Kylie Jenner has a lot going on for someone who's not even out of their teens yet. Her own hair extensions line, a clothing range with Pacsun, a €2.7m house to renovate, and of course her family's reality show.

Now though, it looks as if Kylie and her older sister Kendall might have yet another project up their sleeves, if this new Instagram post is anything to go by.

The reality star posted a picture last night showing herself and Kendall working on what looks to be a new line of clothing, but she refused to divulge any other details. In the two Polaroid snaps, the sisters can be seen looking at mood boards and design suggestions for an unnamed brand.

The photo was captioned, "designing. I've never been more excited for what's to come! Stay tuned this summer."

It's unclear whether the designs are for the girls' existing Pacsun range, for their summer 2015 Topshop collaboration or for something else entirely. Whatever they are, we are VERY excited indeed.

While Kylie and Kendall definitely have a proven interest in fashion, some commenters were quick to point out that clothes design is not all about gazing at mood boards.

"I never knew how easy designing was! Just looking at pictures and picking out your favourite ones!" wrote one follower, with another adding, "This isn't designing lol. You know damn well you're just looking at pics of other ppl's designs and choosing what you like best and you're gonna slap your name on it."

Haters gonna hate…
