Stormi had a rainbow-themed birthday party, complete with multi-colored bunches of balloons and a giant round birthday cake covered in rainbow sprinkles.
"We have all her cousins here, everybody who loves her," Kylie said.
Her sister Kourtney Kardashian posted on her Instagram Story a video of her holding Stormi, writing, "My little Stormaloo how I love you so angel girl. Happy Birthday!"
Kylie also said on her Instagram Story, "We're playing with farm animals." Her BFF Jordyn Woods posted on her Instagram Story a photo of the cake as well as a pic of herself holding two rabbits.
The party took place two days before Travis is set to take the stage at the 2019 Super Bowl in Atlanta. The rapper performed at a Pepsi party for the event on Friday night and gave an onstage shout-out to Stormi.
