Brittany Mahomes arrived at Arrowhead Stadium in Kansas City on Thursday night to cheer on husband Patrick in his season opener game against the Baltimore Ravens.

The personal trainer wore a simple white T-shirt with Alice & Olivia cargo jeans ($495), leaving her blond hair down in waves, pulled half up in braids. She added white sneakers to the low-key look.

She held hands with daughter Sterling, who wore a red dress with the word “Chiefs” embroidered on the chest. She posted a snap from the sidelines on her Instagramy story, all smiles after a lightning delay.

“We’re surviving,” she laughing in an Instagram Story by the sidelines with daughter Sterling, 3, who draped a Chiefs towel over her head as it appeared to rain in the stadium before the game kicked off.

For her part, Sterling looked adorable in a red dress with matching ruffle socks. Her hair was pulled up into two pigtail buns, complete with yellow bows in honor of Chiefs colors, of course.

Mahomes, who announced that she’s expecting her third child, a girl, with the quarterback appears to be all about the pocket-heavy style, choosing a pair of khaki cargo pants with a black feather top to celebrate her 29th birthday over the weekend. The couple also shares 1-year-old son Patrick “Bronze” Mahomes.

Last month, the Mahomeses twinned at a preseason game in the same Ambercrombie & Fitch T-shirt and red Adidas sambas sneakers.

She did not appear to join BFF Taylor Swift in a suite to enjoy the game and cheer on their significant others, with the “Bejeweled” singer arriving ahead of Mahomes in a denim corset, tiny jean shorts and thigh-high red boots.

The mom of three previously attended a preseason game in style, twinning with Patrick in an Abercrombie & Fitch Chiefs T-shirt and the same red Adidas Sambas sneakers.

Mahomes apparently loves to coordinate for game day, previously twinning with Swift in a puffer jacket designed by fellow NFL WAG Kristin Juszczyk.
