Swift and several friends and family members made an appearance in Kansas City to cheer on her boyfriend Travis Kelce at the Chiefs game on Sunday.

On Sunday, Sept. 15, just before the Chiefs took on the Cincinnati Bengals at Kansas City’s Arrowhead Stadium, the “Fortnight” singer, 34, and her mom, 66, were spotted arriving at the game to cheer on the tight end.

After photographers and fans snapped photos of the mother-daughter duo arriving on a golf cart to the field, one detail on Andrea’s outfit stood out as a custom nod to Kelce and her daughter.

She joined Kelce and his teammates to celebrate their win at the Kansas City bar Prime Social that night following the game, with a source telling PEOPLE that “everyone partied hard.”
