Kylie Jenner Celebrates ‘Babies’ Stormi and Aire’s Back-to-Back Birthdays in Sweet Video and Photos: ‘My World’

Kylie Jenner’s “babies” are growing up!

Both of Jenner’s kids are celebrating their birthdays this weekend — as her daughter Stormi turned 7 on Feb. 1 and her son Aire turns 3 on Feb. 2 — and the reality star, 27, is showering them with affection.

On Saturday, the mom of two and style mogul, who shares both kids with ex Travis Scott, rang in the little ones’ milestones with an adorable video on Instagram. In the clip, Stormi hugs Jenner tightly, clinging to her as Aire goes rogue and sticks his eye right in the camera.

“Hi,” Jenner begins in the clip as her daughter smiles and laughs loudly. Aire, meanwhile, yells, “Mama,” and wanders off. After putting his face right up to the camera, he returns to his mom and buries his face into her. 

“Mommy,” he repeats as she tells the little ones, “I love you.”

In the caption, the Kardashians star added another message for the birthday boy and girl. “My world,” she wrote. “Happy birthday to my babies. 🥹.”

Jenner also shared a behind-the-scenes look at Stormi’s birthday celebration: a Hello Kitty-themed birthday sleepover, which kicked off on Jan. 31.

“Setting up for my princess stormi’s bday sleepover 🥹🥹🥹,” the mom of two wrote in an Instagram Stories post over footage of tons of pink, Sanrio-branded food and party favors, from Hello Kitty-shaped waffles to fuzzy slippers.

In the next post, “Nonsense” by Sabrina Carpenter played in the background as the star showed off a tent and balloon-covered area where Stormi’s guests could hang out. Specifically, her pals had the option to get cozy with plush versions of different Sanrio characters and play games like Hello Kitty Monopoly. 

Jenner, who wore her hair pulled back in a Hello Kitty headband, also had some fun with filters with her daughter as they prepared for her guests to arrive.

In one picture, Stormi planted a kiss on her mom’s cheek as the star rocked a filter that made her eyes big. In the next snap, Stormi tried the big-eyed filter on for herself.

Elsewhere at Stormi’s party, there were platters of all-pink treats and Sanrio pillow-covered chairs pushed into tables decorated with pink flowers. Another, larger, table featured Hello Kitty plates and cutlery, plus a giant bouquet of pink balloons, some of which were decorated with the feline’s face.

The mom — who is currently dating Timothée Chalamet, 29 — also reposted some throwback shots of herself and Stormi on Friday before wrapping her daughter’s birthday coverage with a shot of the post-sleepover meals.

To wrap the festivities in the morning, Stormi and her guests enjoyed Hello Kitty waffles, fresh fruit, heart-shaped marshmallows and cotton candy, and for lunch, ate ramen out of pink, Hello Kitty bowls.
