Paying the love forward, Kylie commented on the post, giving Cardi’s daughter a sweet shout-out.

“Thank u for coming beautiful Kulture!!!!!💜💗,” she wrote, as sister Khloé Kardashian added, “What a way to bring in 2! It was so spectacular.”

Cardi’s younger sister went on to share a few more shots from inside the bash, which was filled with amusement park rides, Trolls characters, a StormiWorld merch store and more.

“We had a blast at #stormiworld⛈🌎 💖!!” she captioned one festive post, which featured an image of the pair posing at the entrance to the party: a giant cartoon version of the birthday girl’s face.

Another sweet video showed Hennessy, 24, and Kylie, 22, helping the girls make some arts and crafts as Frozen’s “Let It Go” played in the background.

The extravagant celebration took place a week after Cardi got a sweet shout-out from Kanye and Kim Kardashian West‘s 6½-year-old daughter North.

While spending time with her friends and modeling fuzzy bathrobes from Kardashian West’s Skims shapewear brand, North and the other youngsters explained that they were all members of the “Cardi Crew” with their own Cardi-inspired nicknames.

Adding an extra layer of cuteness, North’s cousin Penelope Scotland, 7½, shared that her pals called her “Cardi P” — and she even had a necklace to prove it.

Shortly after getting tagged in the post, Cardi let the Kardashian clan know just how touched she was by all the love. “This made me feel soo special,” she wrote in the comments section. “I feel soo happy.”

Of course, Cardi is no stranger to the Kardashian-Jenner family.

In August 2018, the “Press” rapper joked that she had become part “of the rich people club” after meeting up with Kardashian West and Kris Jenner for a “late-night house party” at the KKW Beauty mogul’s home — and quipped that she’d be selling one of the famous momager’s napkins on eBay.

Getting in on the joke, Kris, 64, replied, “Yes and I get 10 percent.”
