Chemtrails!!! Kylie Jenner is really concerned about them!
The reality starlet posted a tweet on Monday that was quite wary of these weird white streaks in the sky made by airplanes.

We really doubt she personally wrote the message, because we're sure she knows how to spell "responsible" and use apostrophes correctly, but by reposting it, it appears that she may be worried about them.
Although there's no need! Chemtrails aren't really a thing, Kylie.
They're just hot air from the plane hitting colder air and creating condensation.
The 17-year-old also posted a new image of herself on Tuesday modeling some tiny shorts (and dragging a fur coat in the dirt!) from an upcoming photo shoot, and we just couldn't resist doodling all over it.
