After pushing her birthday back a weekend because of Los Angeles' rain storm, their famous friends and family celebrated the tiny tyke with one serious mega party.
Kylie shared some of the images from inside on Saturday via social media.
The entrance was a giant blow-up of the one-year-old and to get inside the "Stormiworld" themed party you have to walk through her mouth. Obviously, the theme is a play on her rapper dad's "Astroworld" tour.
Inside the party was where the real magic happened.
There were rides, games and fair food on crack including giant pretzels hanging from an umbrella hat worn by a staffer, lemonade with fun straws, mini pizzas with personalized packaging reading "SW" ... and don't even get us started on Stormi's cake.
That family sure knows how to throw one hell of a party!
