At this point Jeffree Star and Kylie Jenner have a history that's messier than Rob Kardashian and Blac Chyna's relationship.
It all started back in 2016 when Jeffree took to Twitter to slam the quality of Kylie's lip glosses (which to be fair were pretty shocking).
But by December 2017 the BFF shopping trips were over and Jeffree once again took to Twitter, this time voicing his opinion on the price of Kylie's makeup brush set.
If that wasn't enough, he posted a review video of the brush set comparing it to something from "The Dollar Tree".
And if you thought Jeffree was done there, think again because in January 2018 he still had A LOT of opinions on that brush set.
Up until this point, the products that Jeffree were reviewing (including that brush set) had been sent to him by the Kylie Cosmetics PR team for free. But it looks like Kylie has finally removed Jeffree from that exclusive list.
From this Tweet alone, I knew it was on.
And, well, he went for it:
Kylie has not responded...yet.
