Brittany Mahomes has made her first game-day appearance of the NFL season!

The soon-to-be mom-of-three arrived for the Kansas City Chiefs vs. Atlanta Falcons game at Mercedes-Benz Stadium in Atlanta, Georgia, in style.

Brittany, wife of Chiefs quarterback Patrick Mahomes, wore a glittery, cowgirl-inspired outfit to the Sunday, Sept. 22 game in Atlanta.

In a post shared to Jackson Mahomes’ (Patrick’s brother) Instagram page, Brittany can be seen in an oversize gray bedazzled Chiefs t-shirt covering her baby bump, black shorts and shiny cowgirl boots in the team’s signature red color.

She even shared a link to her boots and t-shirt on her Instagram Stories, revealing that the top was from the official NFL store and the boots were Feners’ Altura — and the shoes were on sale from Revolve for $252.

Rounding out her look, the Current co-owner held a red and black quilted Chanel purse and had her blonde hair pulled back in two braids, along with a full-glam makeup look.

Although the Mahomes’ kids Sterling, 3, and Bronze, 1, didn’t make an appearance at the game, tons of other celebs stopped in Atlanta (except, notably, Taylor Swift). In a post shared to Instagram by the official Falcons account, everyone from rappers 2 Chainz and T.I., comedian Heather McMahan to hot dog-eating champion Joey Chestnut and TikTok stars Campbell and Jett Puckett could be seen attending the game.

The 29-year-old mother’s latest look follows her 2023-24 season full of stylish ensembles rooting for her husband on the sidelines. At the first two games of the 2024-25 season, she kept her looks classic.

For the season opener on Sept. 5, between the Chiefs and Baltimore Ravens, she wore a simple white tee and cargo jeans with a red and white stripe. She also dressed her 3-year-old daughter in an adorable outfit of a little red dress that has “Chiefs” embroidered on the front in yellow cursive letters.

For the game between the Chiefs and Cincinnati Bengals on Sept. 15, Brittany opted for another classic look, but this time in Chanel.

At the second game, Brittany pulled from the archives and wore a vintage set from Chanel’s 1997 spring collection — a logo slip dress (which she appeared to have altered into a romper). She topped it with a black blazer.

She finished out the look with Chanel loafers, ankle socks, a Chanel logo necklace and hexagonal sunglasses to complement her pulled-up hair.

While Brittany wasn’t donning Chiefs red at the game, her kids, Sterling and Bronze, both wore Chiefs gear in support of their dad. Bronze was outfitted in a tiny Mahomes jersey, while big sister Sterling wore a custom checkerboard dress with “Mahomes” banners and arrowheads.

Brittany isn’t the only supportive significant other on the sidelines. Brittany has been joined by Taylor Swift, who is dating tight end Travis Kelce.

Swift, 34, first wore a statement-making Versace denim set with thigh-high red boots during week one. The following week she sported a red Chiefs jersey dress with black over-the-knee boots and carrying a Louis Vuitton bag.
