On Instagram, the makeup maven, 21, complimented the “Butterfly Effect” rapper’s work ethic alongside photos of Scott, 26, cuddling with their 9-month-old daughter Stormi. In the pictures, Scott smooches Stormi’s cheek as the baby happily pats her dad’s face.
The post, which earned a like from Jenner’s sister Kim Kardashian West, followed Scott’s Astroworld Fest at NRG Park in Houston on Saturday. The event included performances by Lil Wayne and Post Malone.
The Keeping Up with the Kardashians star praised her boyfriend, writing “only the people around you really know how hard you work.”
“I love to watch you make all your dreams come true. your first festival. we’re so proud of you. we love you,” she concluded, punctuating her message with a heart.
“I love you wifey,” commented Scott.

On Sunday, Jenner shared yet another photo of her little girl — this time, posing with mom.
“Ugh i love you so much. a living breathing piece of my heart,” she wrote.
