We also know a lot of Kylie's richness comes from her brands, Kylie Cosmetics and Kylie Skin, which landed her the controversial title of youngest self-made billionaire in history.
So when Kylie posted a video to her YouTube channel giving a tour of the Kylie Cosmetics office, I shouldn't have been surprised at how extra it all is. BUT I STILL AM.
First, Kylie showed off some of the smaller details of the office, like the little bowls of pink Starbursts and the M&Ms printed with her own face.
There's a table full of every Kardashian/Jenner magazine cover ever, except for maybe when Kim was on the cover of K9 magazine.
It was while Kylie was showing us the pink plates and bowls in the communal kitchen area that I realised she was wearing a diamond Kylie Cosmetics logo around her neck.
Then Kylie showed us the Kylie Cosmetics drinks fridge, which contains a variety of coffee creamers, soda, juice, several different kinds of water, and Pedialyte.
She got the video editors to blur out this drink because it's her favourite and it's apparently hard to get hold of, but after an extensive investigation* I have determined it's Guayaki Yerba Mate.
Kylie explained that there's a bar cart in the office at the request of Kris Jenner.
Then she took us into her own personal office, where she displays a vase of flowers made out of money that was a gift from Alexander Wang.
Kylie went on to show several other rooms in the office, like her "YouTube room" where she shoots videos and her "friends and family glam room" where her friends and family go to get glam when they visit.
Then she took us into her ~personal~ green room, which has a connecting bathroom with a giant pink marble shower, a giant fitting room full of mirrors, and Kylie's personal glam room.
You may think the tour would end with all those rooms, but no! First, we have to see the Kylie Cosmetics–branded champagne vending machine, which Kylie herself has apparently never used, but other people have.
And finally we were shown Queen Stormi Webster's playroom, where she had been asleep the entire time, which is a huge mood.
So, in a conclusion that we already knew, Kylie Jenner is rich.
