Starting things off with a bang, the entrance to the party resembled Stormi's dad Travis Scott's Astroworld album art, featuring a giant blow-up replica of Stormi's face that welcomed guests into the venue.
And that's not all as there was even a "Stormi's Gift Shop" merchandise stand for guests.
"I'm not so sure", Jenner coyly replied. He's also set to perform, so we're sure Stormi is somewhere cheering her father on like she did when he graced the Super Bowl stage on February 3. And what a great birthday party! Caitlyn captioned a photo with her daughter, granddaughter and girlfriend, Sophia Hutchins, at the party.
We're loving the way that the satin fabric succeeds in keeping it demure yet...oops, she did it again!
The two were last spotted enjoying a date night on Thursday, as they were photographed leaving the restaurant Cipriani in New York City.
Jenner's older sister, Khloé Kardashian, also stopped by with her daughter True, as did her brother, Rob Kardashian, with his ex Blac Chyna and their little one, Dream.
Think back to your first birthday party.
With the SICKOMODE rapper snuggled into her neck, Kylie, 21, gently held onto his hand making for one of the cutest couples of the night.
DJ Khaled was also in attendance at the event and gifted Stormi her very first tiny Chanel handbag! In January, after Jenner shared a behind-the-scenes look at a sexy swimsuit photo shoot for her collection Kendall + Kylie, Simmons left an incredibly flirty comment, writing, "Come here..."
"See there you are, but there's a guy in front of you, I can hardly see you", DeGeneres jokingly remarked, referring to Simmons.
I know nothing about it.
"My love grows for you a thousand miles a minute", Kylie continued. "Happy first birthday Stormi!".
