Kylie Jenner Throws an Over-the-Top Birthday Party To Celebrate Stormi Turning 5

It's not every day your little girl turns 5, which is why Kylie Jenner spared no expense when putting together a celebration for daughter Stormi's fifth birthday on Wednesday. The party seemed like an absolute rager for the kids and included custom clothing, balloon installations, and more!

The party took place Wednesday.

Guests entered the event by walking through a massive Astroworld-style inflatable featuring the birthday girl's head (and no, this is not the first time Kylie has done this for Stormi). Once the guests made it inside, they were welcomed to the fun by a sea of pink and white balloons, two colors that seemed to be the theme of the event.

Neither the fun nor the inflatables stopped there.

Kylie kept guests busy with another giant rendering of the birthday girl's head, this time as it sat atop a massive rainbow-colored slide.

And there was no confusion over who the guest of honor was, because Kylie had custom clothing created for her kids. (Her son Aire also got a birthday shout-out at Stormi's party because his big day is one day after Stormi's.)

Her cousins all appeared to be celebrating with her.

Stormi's aunts Kim and Khloé were also in attendance with their kids and shared some of the fun on their own Instagram pages.

It looks like all the littlest Kardashian-Jenner kiddos were having a blast celebrating their cousin as she hit this birthday milestone, and we totally get it — this looked like the best party ever.

Even the cake was an elaborate affair.

Long time Kardashian followers knew better than to expect Stormi to be celebrated with a store-bought sheet cake, but we were still blown away with just how detailed the little girl's birthday treat ended up looking.

Kylie had a baker put together a stunning floral styled piece that included a mountain of sweet blooms in all the colors of the rainbow.

Travis Scott's art may have been the inspiration for the theme.

It looks like Kylie may have gotten her party inspo from one of Travis' album covers, even though the pair recently called it quits — again. Now that StormiWorld has become a tradition, we can't wait to see what next year's party looks like!

It appears the big bash was a total hit. Stormi and her guests are going to remember this party for many years!
