Brittany Mahomes brings daughter Sterling, two, and son Bronze, 11 months, to cheer on husband Patrick Mahomes alongside new bestie Taylor Swift at Chiefs game

Brittany Mahomes was ever the doting mom on Sunday as she brought her two kids along to cheer on husband Patrick Mahomes, along with new girlfriend Taylor Swift.

The Kansas City Chiefs quarterback’s wife, 28, joined the Bad Blood hitmaker, 33 – who is currently dating Travis Kelce, 34 – during the Chiefs vs Chargers game at Arrowhead Stadium in Missouri.

Brittany accompanied her 11-month-old son Patrick “Bronze” Lavon III and 2-year-old daughter Sterling Skye.

She seemed to be having a blast during the game, as she danced with Swift while holding baby Patrick on her hip.

They proved to be a good luck charm for the Chiefs, who won 31-17 against the LA Chargers.

The retired women’s soccer star wore a red vest in support of her boyfriend and his team.

Underneath she wore a white long-sleeved top and light blue jeans. Brittany wore her light blonde locks down the middle for the occasion.

Meanwhile, Sterling also wore the red sweater in support of her father, while Patrick wore a white onesie.

Swift also supported the team with a red Chiefs sweatshirt.

And Kelce and Mahomes put on a show, with the tight end scoring a touchdown on the stroke of halftime and racking up 143 receiving yards in the first half alone — the most of his career for a first period — which Swift and her new boyfriend, Brittany, resulted in a reason to celebrate.

The two “WAGs” have clearly bonded during their time together in the stands and have grown so close that they even created their own special handshake, which they broke out after the Chiefs’ first touchdown against Marquez Valdes-Scantling.

The two new friends enjoyed enjoying the action together, and even started dancing during the first half.

Swift, with a drink in hand, and Brittany, holding her son in her arms, swayed back and forth as they bumped their heads in time.

The 12-time Grammy Award winner enthusiastically cheered on her NFL friend.

In a tense moment in the first half, she even became so animated that she hung out of the suite window.
