Mom, dad, and Stormi were seen dancing along to a live performance of "Baby Shark" performed by life-sized characters and there were adorable mini pizzas, French fries, and other treats served. Caitlyn captioned a photo with her daughter, granddaughter and girlfriend, Sophia Hutchins, at the party.
In a series clips on her Instagram story, she said: "Alright so, we were supposed to have Stormi's birthday party this weekend".
At the party, Kylie, Kim, Kris and Khloe were all together (with their children) to celebrate the toddler's birthday.
The two were last spotted enjoying a date night on Thursday, as they were photographed leaving the restaurant Cipriani in New York City.
Stormi also posed with her cousins True and Kourtney's son, Mason Disick, 9, while cuddling up to some life-size stuffed animals.
Ariana Grande a no-show despite winning first Grammy Award Ariana Grande was not happy when Mac Miller didn't win his Grammy. "Congrats to all the nominees", she tweeted Sunday. For music's night of nights, The Grammys , all eyes were on the big categories to see if there would be any upsets.
DJ Khaled was also in attendance at the event and gifted Stormi her very first tiny Chanel handbag! Because even at the age of one, Stormi knows the importance on monetising your brand.
Kylie and the rest of the Kardashian clan shared photos on Instagram to share videos and picture of Stormiworld - a carnival dedicated to her daughter!
"How did I get so lucky to have such a sweet, smart, happy baby", she began.
"I know you won't remember much about the first year of your life but i pray that you'll never forget to keep sharing your joy and laughter with the world", she added. My love grows for you a thousand miles a minute.
As always, people following the party on social media gave their thoughts on Jenner and Scott's over-the-top party for their little girl.
Taking inspiration from her baby daddy Travis Scott's Grammy nominated album, Astroworld, Kylie pulled out all the stops for the bash, which included a giant inflatable entrance in the shape of the tot's face - a direct reference to Scott's album cover.
