Swift was left to console Brittany after watching her new friend’s husband, Chiefs quarterback Patrick Mahomes, strugglе throughout the loss.

As Las Vegas defeated their division rivals, Patrick Mahomes threw a pick-six in the second quarter and generally played below his lofty standards.

And the Kansas City passer’s wife was visibly upset by the outcome, looking shell-shocked and putting her hands to her face as Swift rubbed her shoulder.

The loss marked the second loss for NFL beau Kelce and the Chiefs with her in attendance, and the pop star appeared deflated.

Brittany was probably irritated by her husband’s obvious frustration. As the final seconds ticked away, cameras caught quarterback Patrick Mahomes on the sidelines looking teary-eyed.

The broadcast zoomed in on Mahomes, who had tears in his eyes and bit his lip as he desperately tried to keep them at bay as the Raiders began to celebrate their holiday victory.

Earlier in the game, the signal caller had expressed his emotions in a slightly more аggressive manner.

As the reigning Suρer Bowl champions struggled to break down the Raiders’ defense, he was seen berating his оffensive linemen.

Since the songstress began her high-profile relationship with the Chiefs tight end and began attending his games alongside the longtime WAG, the two have quickly formed a close friendship.

Taylor and Brittany wore matching red Santa hats for the Christmas Day game, with Taylor’s embroidered with a ’87’ on the front and Brittany’s with a ’15’ in tribute to their partners’ respective jersey numbers.

Patrick Mahomes of the Kansas City Chiefs appeared to cry during Monday’s loss.

Swift and Kelce have been almost inseparable since they made their relationship public, and they even debuted a personal handshake to celebrate Chiefs touchdowns in October.

Brittany also appears to have been accepted into Taylor’s inner circle, as she dined with Selena Gomez, Gigi Hadid, and Sophie Turner last month in New York City.

The former collegiate soccer player also flew into Green Bay with Taylor on the Anti-Hero hitmaker’s private jet earlier this month and appeared to have lent Swift a red Teddy coat she previously wore to a game for the frigid game against the Packers.

While Brittany did not mention Taylor in her post, the timing corresponds with their growing friendship.

Swift arrived in Kansas City on Monday with her parents – and Santa Claus.

Even as the reigning Suρer Bowl champions struggled to break down the Raiders’ defense, Kelce was a key weapon once again.

The tight end had one particularly impressive carry that had Arrowhead Stadium fans on their feet. Swift could be heard screaming ‘Travis!’ and ‘Oh my God!’ as he carried the ball up the field.

However, as the Chiefs began to slump after their loss, the two-time Suρer Bowl champion was seen letting his frustrations get the best of him.

Kelce returned to the sidelines and threw his helmet in disgust after the Chiefs gifted their opponents back-to-back defensive touchdowns in an NFL record seven seconds.

The helmet bouncing off the turf and into the Arrowhead Stadium stands was caught on camera by CBS cameras.

The Grammy winner was also seen pressing up against the glass with a young girl.

On Monday, the singer flew across the country to see her boyfriend play for Kansas City.

Swift’s private plane took off from Nashville around 8 a.m. ET and landed at Charles B. Wheeler Downtown Airport shortly after 10 a.m. local time.

She was then whisked away to the stadium, making the 12-mile drive with her team before arriving at Arrowhead around 11 a.m.

She was escorted into the stadium on a VIP golf cart alongside another special guest: Santa Claus, who carried a sack and wore a special Chiefs hat.

‘Merry Christmas!’ Swift said as she walked into the stadium, while Santa Claus rang a bell. She was greeted by adoring fans who screamed as she walked towards her suite.
