The Kansas City Chiefs earned a dramatic victory over the Cincinnati Bengals on Sunday, and their most famous fan was on hand to celebrate the win.

Taylor Swift, who is dating Chiefs star tight end Travis Kelce, celebrated with her friends in a box seat at Arrowhead Field. The pop star was also in attendance for Kansas City’s win over Baltimore in Week 1.

Kelce didn’t exactly play his best on Sunday, managing just five yards on a pass reception and one yard on a rushing attempt, but the Chiefs’ win was probably all that mattered to him.

It was a slow offensive night for the Chiefs and Bengals considering how many points have been scored in this matchup throughout the year.

The two teams scored field goals in the first quarter before each side scored a touchdown early in the second quarter. The Bengals then scored two more field goals to make the halftime score 16-10.

In the second half, Kansas City and Cincinnati played out a thrilling duel, with the Bengals leading 25-23 for most of the fourth quarter. Trailing by two points and with time running, the Chiefs managed to get within field goal range with just seconds left, and Harrison Butker sank a 51-yard field goal for the win.

This dramatic ending was a huge reason to celebrate for Swift, and she hopes to continue celebrating all year long while cheering on Kelce and the Chiefs.
