Kylie Jenner brings kids Stormi, 5, and Aire, 1, to cousin True’s early birthday bash featuring adorable cake and piñata

KYLIE Jenner has attended her niece True's fifth birthday party with her two children - and she shared the whole event with fans.

On Saturday, Kylie, 25, posted a minute-and-a-half-long TikTok video that documented the beginning, middle, and end of her sister Khloe Kardashian's, 38, daughter True's, 5, party.

Then, the beauty mogul showed off her and her daughter's party outfits in a mirror.

Stormi was dressed in a bright lime green tule dress while Kylie wore a muted tank top with tight cargo pants.

When they arrived at True's party, they were greeted with a pastel rainbow balloon arch that teased the theme of the party.

Inside, Kylie showed off her son Aire, 1, as she held him in her arms.

The Hulu star also gave fans a look at the creative under-the-sea theme decorations which made partygoers feel like they were actually under the sea.

Multicolor balloons floated above the heads of guests as a giant pink octopus made of balloons watched over the party.

The cake perfectly matched the theme with adorable sea creatures and seaweed made of frosting covering the fondant.

ACTIVITY CENTRAL

The kids at the party were able to make their own slime. Stormi's was the same color as her dress, a lime green.

The Keeping Up With the Kardashians alum also shared a clip of Stormi attacking the piñata with all the force the kiddo could muster.

The youngster hit the piñata so hard, Khloe could be heard cheering her on and saying, "heck yes!" to her niece.

After the pinata was broken and all the older kids were scrambling for candy, Kylie showed herself reaching down and picking a few pieces up off the ground.

"Oh, gonna get some candy for my baby," the mom-of-two said.

Stormi could also be heard yelling: "My bag is so full!"

The video ended with Stormi's grandma Kris, 67, standing next to her grand baby in a pantsuit in the exact same neon green as Stormi's dress.

PARTY #1

Earlier this week, Khloe threw True another birthday bash with some of her famous cousins.

The Good American founder posted a video of the party on her Snapchat story. In the clip, True played in a ball pit with her cousins Dream, six, Psalm, three, and Chicago, five.

The kids chatted and smiled at the camera from the ball pit, while Can't Stop the Feeling by Justin Timberlake played in the background.

One detail, however, caught fans' eyes after Khloe shared the throwback post from last April.

While the bottom level of the ball pit held traditional plastic balls, the majority of the space was taken up by layers of cat Squishmallows.

One of the 38-year-old's followers reposted the party pic to Reddit, with the caption: "This 'ball pit' at True’s bday party…"

People were quick to comment on the expense of the sought-after toys.

One person said: "... I really love how squishmallows show your wealth."

Another added: "This is just bizarre. Never thought I’d add 'misuse of squishmallows' to things this dreadful family has ruined."
