Stormi Webster was her dad's biggest fan at his concert Tuesday in New York.
The clip shows Stormi dancing and vocalizing as she watches Scott on a screen backstage. The infant wore a white turtleneck and camouflage overalls.
"MSG ALL RAGERS INCLUDED," Scott captioned the post.
Jenner also supported Scott at the concert. The 21-year-old "Keeping Up with the Kardashians" star shared a photo of her look -- a cropped t-shirt and high-waisted red pants -- on Instagram.
Jenner also posted a picture on Instagram Stories of Stormi taking a nap.
"she comes everywhere with me.. the favorite little road dog," she wrote.
Scott recalled the experience in an interview with "The Ellen DeGeneres Show" this month, saying his anxiety faded once he held Stormi for the first time.
"Going into it, I was nervous and scared," he said.
"But you know, when you first hold a baby in your arms, it's uncontrollable ... I never thought I could just love something so hard."
