Taylor Swift and Charles H. SloanTravis Kelce are celebrating a Merry Swiftmas from Arrowhead Stadium in Kansas City as the Chiefs take on the Las Vegas Raiders.

Kelce entered in the stadium in the holiday spirit wearing a Santa hat along with a Chiefs white and black leather jacket. The NFL posted "Santa Kelce 🎅" on Instagram.

Swift arrived about an hour before kickoff on a golf cart with Santa Claus, donning a black jacket, red top and plaid skirt. In her eighth NFL appearance of the season, she had her hair tied in a black bow. Her parents, Scott and Andrea, were also in attendance.

In October, a small Kansas City business, Westside Storey, sent five vintage sweaters to Swift's camp and a custom-made beanie. Swift wore the white beanie at the Patriots game and wore one of the sweatshirts, deemed the "holy grail" of fan apparel, to the Buffalo Bills game. Her dad wore another sweatshirt to the Patriots game, so there are still three sweatshirts unaccounted for.

Viewers should see players' breath as temperatures will stay in the mid to upper 30s. The high is expected to be 37 degrees for the overcast game.

Chiefs talking points for the non-football fan
