She knocked it out of the park — err, stadium.

Brittany Mahomes, 29, looked every bit the football WAG as she cheered on her husband, Kansas City Chiefs quarterback Patrick Mahomes, at his game on Oct. 20 against the San Francisco 49ers.

The social media star, who is expecting her third child, turned up at Levi’s Stadium in Santa Clara rocking a bump-hugging black romper underneath a customized denim jacket.

Her outerwear was adorned with “Chiefs” on the front, as well as “Mahomes” and her husband’s number, 15, on the back.

Her accessories — brown suede cowboy boots, a clear rectangular bag, and two white hair bows — were equally as statement-making.

The Sports Illustrated Swim star shared images of her look online, captioning an Instagram post, “6-0 BABYYYYYY🔥,” shouting out the Chiefs’ 28-18 win last night and their undefeated streak.

“More on the way!!! (Wins that is 🙂) 🔥🔥🔥,” wrote @kelcebrothers, a fan page for Patrick’s teammate, Travis Kelce, and his brother, Jason.

Other users pointed out her growing baby bump. “THE BUMP IS SO CUTIE,” said one person, while another commented, “Cutest bump ever!”

In July, high school sweethearts announced the news of their third child (a girl!) via an Instagram video featuring their two kids, daughter Sterling, 3, and son Bronze, 1. “Round three, here we come 🤍,” it said.

Meanwhile, Travis Kelce channeled girlfriend Taylor Swift’s “Midnights” era with his pre-game look, sporting a royal blue corduroy set.

The pop star was unable to attend the game as she continued her Eras Tour in Miami — but the Kelce family was supportive, with Jason and Kylie Kelce bringing their daughters as well as mom Donna Kelce.

Taylor even gave a shout-out to Travis and his team, changing lyrics to “Karma” to nod once again to “the guy on the Chiefs.”
