Brittany Mahomes Shares Fun Photos from Kansas City Chiefs' Holiday Party: 'Falalalalala'

The NFL stars and their significant others went all out for the team's annual festivities in Kansas City

Brittany and Patrick Mahomes are ready for the holidays!

The Kansas City Chiefs held their annual holiday party at pop-up bar Miracle in Kansas City on Friday night, and Brittany, 28, shared photos from inside the team's festivities.

In one photo, Brittany and Patrick, 28, are wearing matching reindeer onesies as they pose at a table surrounded by Christmas decorations.

The couple, who share a one-year-old son Patrick "Bronze" Lavon Mahomes III and daughter Sterling Skye, 2, completed their matching looks with antler headbands, and Brittany paired her onesie with a pair of Uggs while Patrick matched his to a pair of sneakers.

"Falalalalala," Brittany wrote in her caption, adding a Christmas tree emoji.

In a second photo Brittany posted on Instagram, she and Patrick posed with Chiefs tight end Blake Bell and his wife, Lyndsay Bell. Lyndsay and Blake also sported matching looks, indicating that many players and their dates wore coordinated outfits.

Chiefs tight end Travis Kelce was spotted by locals at the party, and news circulated online that Taylor Swift accompanied her beau to the team’s gathering.

In one photo, Swift was pictured chatting to Brittany, whose back was facing the camera.

As photos circulated online, one Chiefs fan claimed on X (formerly Twitter) that the couple wore matching holiday sweaters, in line with the party’s theme, which featured a squirrel — a comical reference to one of Kelce's now-viral old tweets in which he misspelled the word.

The pop-up bar also reposted a series of photos on Facebook where a customer claimed that Swift was at the bar on Friday night at the same time as she was. “Hung out with Taylor Swift here last night and by hanging out I mean she was there and so were we,” the post’s caption said.

An onlooker told PEOPLE that Swift’s holiday song “Christmas Tree Farm" played at the party — which took place in a semi-private back room of the venue — and confirmed that the singer was in attendance at the celebration with her beau Kelce, 34.

"Everyone looked happy and festive" and there was "great energy" at the party, the onlooker said.
