To some fans, the seductive photo came as quite a shock, considering multiple members of the KarJenner clan — including Stormi’s aunt Kim Kardashian West and aunt Kendall Jenner — were using their social media to celebrate the second-youngest member’s first year.
But one particular follower was not afraid to bring it to the Keeping Up with the Kardashians star’s attention.
“the most touching birthday wish for stormi,” the user sarcastically commented on Kourtney’s sexy shot.
In response, Kourtney clapped back: “she doesn’t have Instagram yet, but Stormi if you’re reading this Happy 1st Birthday!”
Shortly after the comment exchange, Kourtney posted a video to her Instagram Stories in honor of her niece’s 1st birthday.
In the short clip, Kourtney held Stormi on her hip as they looked into a mirror together. “Look, who is that?” she whispered to Stormi, who is donned her Burberry baby dress.
“My little Stormaloo how I love you so angel girl,” she wrote in the corner of the video. “Happy Birthday!”
Kourtney Kardashian’s comment back to the fan
Proud grandma Kris, 63, shared a gallery of photographs of Stormi and Kylie from the baby girl’s first year, writing in her post’s caption, “Happy birthday to our little angel Stormi! You bring us so much joy with your sweet smile and precious laugh. You are such a beautiful blessing and I love you so very much!”
In maybe the cutest photo of all, Kendall, 23, planted a kiss on her smiling niece’s cheek, captioning the adorable image, “Sweet, tiny noodle! your energy is powerful, i hope the world offers you nothing but beautiful things. i love you Stormeroo! happy 1st birthday 🦋”
Along with her extended fam, Stormi’s parents Kylie and Travis Scott also posted messages to their daughter on social media.
“How did i get so lucky to have such a sweet, smart, happy baby. i just couldn’t have dreamt you up, storm. i wish you could stay this little forever and i could protect that contagious smile and laugh of yours,” the makeup mogul, 21, captioned the heartwarming slideshow on Instagram.
“I know you won’t remember much about the first year of your life but i pray that you’ll never forget to keep sharing your joy and laughter with the world.”
“My love grows for you a thousand miles a minute,” Kylie continued. “Every day with you is the best day of my life. happy birthday to my angel on earth. 🎈”
Added Travis, 26: “ITS MY QUEEN ,MY HEART, MY AIR , MY EVERYTHING. STORMI’S BIRTHDAY TODAY. I LOVE U SO MUCH BABY,” the rapper wrote, tacking his heartfelt message on to a gallery of photos and clips.
The luxury vacation saw the gals posing together while wearing matching neon-green swimsuits, frolicking on the beach, spending time on the water aboard a boat and more.
Kylie first started thinking of how she wanted to celebrate Stormi’s first year of life when she hit the 5-month mark in June.
But after months of planning of her birthday bash, however, Kylie revealed on her Instagram Stories Friday that the party was not happening due to the inclement weather.

“Alright so, we were supposed to have Stormi’s birthday party this weekend,” she explained. “It’s not happening because it was supposed to rain and it’s not raining anymore.
Of course, rain or shine, Stormi’s big day couldn’t end without a celebration.
“It didn’t end up raining, but better safe than sorry,” Jenner said. “We have all her cousins here [and] everybody who loves her. We’re playing with farm animals.”
Jenner then shared videos and photos from Stormi’s impromptu party, which included a massive rainbow sprinkle-topped cake, an adorably decorated table with lavish balloon bouquets, rainbow placemats and party cone hats, and farm animals.
