Koa James is already his dad's biggest fan!

On Sunday, Kealia Watt shared an adorable picture of her and husband JJ Watt's newborn son Koa marking his "first game day" as JJ's NFL team, the Arizona Cardinals, played against the Minnesota Vikings in an away game.

In the cute snap on Kealia's Instagram Story, the new mom, 30, cradles her baby boy as he sports a red Cardinals onesie with JJ's name and jersey number on the back. He also wears a black beanie as he rests his head against Kealia's chest.

"Koa's first game day ❤️ Let's go daddy!!! @jjwatt," Kealia wrote, thanking fellow new parents Zach Ertz and Julie Ertz for Koa's onesie.

JJ, 33, also posted an adorable tribute to his baby boy on his Instagram, showing off a pair of his football cleats printed with Koa's name, date of birth and baby footprints. "Purpose," he captioned the picture.
