While there was no Stormi World celebration this year due to the ongoing coronavirus (COVID-19) pandemic, Jenner, 23, still managed to go all-out in celebration of her daughter's third birthday on Monday.

The Kylie Cosmetics founder shared several photos from Stormi's birthday party on her Instagram Story, explaining that she'd decided on a scaled-down fête attended by her daughter's cousins.

"Stormi World 3 is cancelled for obvious reasons," Jenner said in a video on her Story. "But I still went all-out for Stormi at my house, and we are just doing a cousin party with all her cousins and the family, which will be still just as amazing."

In addition to an ice-cream cart, the party also had a candy shop, a Raising Cane's food truck, an inflatable slide and Stormi-themed merch. A dining table was adorned with multi-colored balloons and had a castle-shaped backdrop. There were also bubbles and a carriage made completely out of balloons. Guests were welcomed at the entrance of Jenner's home with balloons that read "3rd Times a Charm."

Later, Jenner showed Stormi all dressed up in a puffy pink dress and tiara, while Jenner's sisters Kourtney Kardashian, Kim Kardashian West and Khloé Kardashian all shared photos from the party on their own Instagram Stories, suggesting that nearly all of Stormi's cousins were in attendance.
