The mother-of-two was in the stands at SoFi Stadium to watch the Chiefs narrowly beat the Los Angeles Chargers 13-12.
And it was her choice of attire that caused a stir with fans after wearing a different outfit than perhaps she normally does.
Neither Mahomes nor Travis Kelce were picked to play as Andy Reid rested his star names ahead of the playoffs, with the Chiefs already guaranteed of their postseason status.
There was nothing outrageous about her clothes, far from it. Brittany chose an oversized black jacket to cover her white crop top.
She also wore high-waisted black jeans that flared at the bottom with black shoes, posting her look to her Instagram stories with the caption: ‘The golden light’.
It should come as no surprise that fans rated her look. Brittany is a huge star and inarguably the most recognizable NFL wife in the sport today, although her new friend Taylor Swift may be overshadowing her presence a little.
With Swift a few miles away at the Golden Globes awards, Brittany was able to dazzle in the LA sunshine on Sunday afternoon and clearly wasn’t feeling too exhausted from the previous night.
On Saturday, she was spotted out on the town with Swift and fellow NFL wife Lindsay Bell, who is married to Chiefs tight end Blake Bell.
The trio went out for dinner and it was Mahomes and Swift who decided to dress in all black as they partied out in LA before the Golden Globes, which Swift was nominated for.
Their friendship has blossomed from watching games together at Arrowhead Stadium, with the four of them – Taylor, Brittany, Travis and Patrick – all going on a double date in December.
It remains to be seen if they will engage in such social events when the playoffs begin, however, with the Chiefs aiming to make the Super Bowl for a second year running.
