It's been a rough week for the LipKit queen!

Kylie Jenner is getting totally trashed for charging a whopping $360 for a set of makeup brushes from her cosmetics line, and she reportedly blames the backlash on mom Kris Jenner!

"Are the new @kyliecosmetics makeup brushes made out of animal hair? Is that why they’re so expensive?? B*TCH I’M STILL DUMBFOUNDED!!!!” YouTuber Jeffree Star tweeted, echoing the sentiments of thousands of fans.

The reality star-turned-businesswoman is pissed over the way her momager chose to market the product, and is worried the criticism could hurt her brand.

"Kris is in on every decision Kylie’s makeup company makes, but this is one false step that Kylie argued over and blames her momager for. Kylie is livid over the blowback from her fans over a decision that Kris thought was best," a source dished to Hollywood Life.

'Kylie feels it was an off-brand marketing decision that priced out her core market and fans. She regrets it, but has vowed to follow her own intuition more in the future,” the source added.

No wonder Kylie Cosmetics is on track to become a billion dollar empire!
