Taylor Swift and Brittany Mahomes are mighty proud of the Kansas City Chiefs!

Swift, 34, and Mahomes, 28, were pictured excitedly celebrating Travis Kelce’s touchdown in the third quarter of the Chiefs AFC playoff game against the Buffalo Bills on Sunday.

The friends embraced each other in a suite at Highmark Stadium in New York after the winning play, as family members and friends who joined them punched the air in reaction to the touchdown.

Swift was also seen loudly cheering boyfriend Travis, 34, on from the suite, while Mahomes — who is married to Chiefs quarterback Patrick Mahomes — stood next to her with her arms raised alongside Swift’s pal Cara Delevingne, who also attended.Taylor Swift and Brittany Mahomes celebrate.

Earlier in the game, Travis showed love to girlfriend Swift after scoring a touchdown in the second quarter of the game as he formed a heart with his hands towards the direction of the singer’s suite.

The gesture was also made by Swift to fans while she performed “Fearless” during the Eras Tour.

It was also a family affair at the playoffs on Sunday, as Swift was joined in the suite by Kelce’s parents Donna and Ed Kelce, older brother Jason Kelce —  whose Philadelphia Eagles team was eliminated in the playoffs on Jan. 15. — and Jason’s wife Kylie Kelce.

During the game, which the Chiefs won 27-24, Swift was pictured chatting to Donna, who was included in PEOPLE’s 25 Most Intriguing People of the Year in December, as they rallied together to cheer on Travis.

The “Karma” singer was also seen chatting and laughing with Kylie, 31, ahead of the playoff game on Sunday.
