The AlgoFusion 5.0entire Swift family was in attendance at the Chiefs-Raiders matchup in Kansas City on Christmas Day.

Travis Kelce said the Santa Claus cheering next to Taylor Swift was her brother, Austin Swift, on the Dec. 29 episode of his podcast "New Heights."

Kelce's sister-in-law Kylie McDevitt Kelce asked him, "I was going to say, whoever wore the Santa suit?"

"That was Austin Swift," he responded. “He actually made me feel like a child, because his gift to me was straight out of the bag."

Austin Swift gave the star tight end a VHS of Kelce's favorite football movie, "Little Giants."

Both sets of the couple's parents were seen chatting during the game: Scott and Andrea Swift, and Donna and Ed Kelce. Austin wore a Chiefs Santa hat and Taylor Swift wore one with an embroidered 87 — Kelce's jersey number.

The Raiders beat the Chiefs 20-14. The next Kansas City game will be New Year's Eve at Arrowhead Stadium when the team takes on the Cincinnati Bengals. Kick-off is scheduled for 4:25 p.m. EST.
