Brittany cheered on husband Patrick Mahomes at the Christmas Day matchup between Kansas City and Las Vegas

Brittany Mahomes is putting a festive spin on her game-day style.

The 28-year-old spent Christmas Day cheering on her husband, Kansas City Chiefs quarterback Patrick Mahomes, as his team took on the Las Vegas Raiders at Arrowhead Stadium in Kansas City.

Although the game ended in a loss for the Chiefs, Brittany didn’t let that stop her from wishing fans a Merry Christmas on Instagram. She shared a gallery of photos from the day, showing off the sweater and Santa hat she wore while carrying daughter Sterling, 2 on the sidelines. Their son Bronze, 13 months, joined his mom and sister in a stadium suite.

In another photo, Brittany carried Sterling in an Arrowhead Stadium hallway. She also included a picture of herself with Patrick before kickoff. Brittany’s Santa hat had Patrick’s number, 15, stitched onto it, while Sterling’s hat had “KC” stitched onto it. (Fellow Chiefs superfan Taylor Swift sported a similar one, featuring boyfriend Travis Kelce’s number, and could be cheering in a box alongside Brittany.)

While her husband may be making big plays on the field, Brittany is making some of her own in the stands, thanks to her trendy game-day looks. The mom of two has emerged as a style standout in the NFL world, with a little help from her famous friend Taylor Swift, who always brings the spotlight when she attends Chiefs games in support of beau Travis Kelce.

From casual to dressy, Brittany is always mixing it up. At the Chiefs-Patriots game on Dec. 17, she wore her chicest look yet, a black miniskirt with a matching turtleneck and black thigh-high boots. She topped it with an ivory statement coat customized with “Mahomes” in black letters across the back. Adding a pop of color, she carried a cherry-red Dior box bag.

Last month, Brittany went for a sportier look that showed off her team spirit. While she cheered from the sidelines — and even gave her husband a good luck smooch before kickoff — Brittany wore white pants detailed with pockets, red patches and emblems with her husband’s number. She paired the pants with a fitted white sweater top and a puffy white jacket.

Since Swift, 34, began dating Kelce, also 34, Brittany and the “Karma” singer have been spending a lot of time together, whether it’s watching the on-field action from a stadium suite or enjoying a night out on the town with friends. The two were even spotted doing their own special handshake at the Chiefs-Chargers game in October.

However, Brittany recently spoke out about how all of the newfound attention on her has brought out the trolls on social media. In a post on her Instagram Story on Dec. 19, the KC Current owner said there has been a significant uptick in negative comments coming her way on the popular app.

“Recently there has been ALOT more rude a– people on here, waaaay more then[sic] normal,” she said.

“I’m not sure where y’all came from, but you should probably go back to where you came from…please,” she added.

Brittany also opened up about dealing with the glare of the spotlight in the Netflix docuseries Quarterback, saying it was something she had to adapt to when Patrick — whom she began dating in high school — was first drafted into the NFL in 2017.

“I was not prepared for this,” she said of the attention on the couple. “And at such a young age. We were in love and I loved him with all of my heart. But, you know, I didn’t expect it to skyrocket this soon, and us kind of just being thrown into the fire like this.”
