Buffalo Bills quarterback Josh Allen may have crossed enemy lines by going to see famed Kansas City Chiefs fan Taylor Swift’s show in nearby Toronto this weekend.

Makenna Allen turned heads on Instagram by posting a picture of herself at Swift’s Eras Tour on the other side of the New York-Ontario border. The NFL star’s kid sister sported a sparkling silver-sequin mini dress with some equally ornate boots while attending the event with two friends.

Later she posted on Instagram that the show was ‘the best night.’

Swift did not attend Sunday’s game in Orchard Park, New York, which is a little more than a two-hour drive from Toronto.

And maybe that’s for the best, seeing as the Kansas City Chiefs’ bid for an undefeated season was spoiled by Allen & Co. Ultimately Patrick Mahomes’ last-minute pᴀss to Mr. Taylor Swift, Travis Kelce, was intercepted by Bills linebacker Terrel Bernard, to seal the 30-21 victory for Buffalo.

A three-sport star in high school, Makenna attended the University of Arizona before beginning her career as a head recruiter at a training center in Tennessee, according to her LinkedIn profile.

Unlike Swift, Makenna did attend Sunday’s game in Orchard Park, where her brother tossed for 262 yards and a touchdown.

Most importantly, Allen ran for a 26-yard touchdown on fourth down with 2:17 left to put Buffalo in position to win on Sunday.

Mahomes and Chiefs were the NFL’s last undefeated team and finally ran out ways to eke out one-score victories and overcome second-half deficits. The Chiefs had won 15 straight, including playoffs, since they fell 20-14 to the Las Vegas Raiders on Dec. 17, 2023.

The Bills have won six straight and moved closer to their sixth straight AFC East тιтle.

Buffalo has defeated the Chiefs in four straight regular-season meetings, though Kansas City holds the postseason edge, having won the past three matchups dating to 2020. And it wouldn’t be a surprise if the teams met again in January.

The packed stadium erupted in chants of ‘MVP!’ as the videoboard showed replays of Allen’s touchdown. Bills coach Sean McDermott opted to go for it on fourth-and-2 instead of kicking a field goal for a five-point lead. Allen faked a pᴀss to his left and then broke up the middle, where he bounced off two Chiefs defenders before crossing the goal line.

The rushing touchdown was the 58th of Allen’s career, moving him into second on the Bills list, one ahead of O.J. Simpson, and seven behind Thurman Thomas. Allen’s two-touchdown outing also increased his total to 244, tying Jim Kelly for first in team history.

Buffalo’s defense ended Kansas City’s desperate final drive when Bernard intercepted Mahomes.

Mahomes finished 23 of 33 for 196 yards with three touchdown pᴀsses — two to тιԍнт end Noah Gray and another to Xavier Worthy — and two interceptions.
