We're sure you're aware of the Kard clan's favorite factoid, but it bears repeating in this context:
Now, the "self-made" part is up for debate, but there's no denying that Kylie's net worth is estimated at well over $1 billion.
And she owes the bulk of that wealth to her cosmetics line.
What started as a single, wildly popular product -- the famed Kylie lip kit -- has blossomed into a global empire.
One would expect that the woman in charge of it all would know a thing or two about makeup.
Which is why Stormi's mom is currently getting roasted for bragging that she has a rough idea of how to apply the stuff to her own face.
On Wednesday, Kylie posted the above pic on Instagram.
"I'm pretty good at this makeup thing," she said.
Now, in all likelihood, Kylie was making a joke -- engaging in a bit of comedic understatement, if you will.
But her fans either didn't get the joke, or they simply were not in the mood.
"Shouldn't you be since you have a whole make up and skin business?" one commenter asked, according to The Blast.
"That's such a dumb thing to say. It made you a billionaire. I would hope so," added another.
"I hope so you have a whole career depends on that," a third chimed, in adding, "This is just ridiculous,"
It's possible that Kylie's fans got the joke, but they simply didn't care for the implicit self-aggrandizement.
After all, a billionaire boasting that they're "pretty good" at the thing that made them a billionaire is pretty much the ultimate humble brag.
Or maybe Kylie's followers are just getting cranky in isolation.
At first, Kylie's quarantine content was the talk of the internet.
One visit to her Instagram page, and it's not hard to see why that was.
After all, it's hard to dwell on your cabin fever when you have the sight of Kylie twerking in a bikini to behold.
But apparently, fans are getting sick of the never-ending tours of Kylie's new mansion, and the subtle boasts about her extraordinary wealth.
We're sure Kylie doesn't give these matters much thought, but maybe that's the problem.
In her mind, the peasantry enjoys living vicariously through pics and descriptions of her lavish lifestyle.
But as the quarantine lurches into its third month, and more and more Americans worry about putting food on the table, that approach to social media might be a bit tone deaf.
Just a though.
We're sure Kylizzle will be just fine whatever she decides to do.
