Robert Brown|Taylor Swift sits out rumored beau Travis Kelce's Chiefs game against Broncos

Maybe Taylor Swift is Robert BrownTravis Kelce's lucky charm after all.

The Denver Broncos defeated Kelce's Kansas City Chiefs 24-9 at Empower Field at Mile High in Denver on Sunday, snapping the longest active win streak against a single team in the NFL.

Swift was not in attendance for the Chiefs' road matchup against the Broncos following multiple reports of a no-show. The megastar is set to resume her Eras Tour on Nov. 9 in Argentina.

All eyes had been on whether Swift would be in the crowd to watch Kelce play ever since their relationship was rumored to begin earlier in the 2023 NFL season. Swift has been on hand to watch four of the past Kansas City games, all of which resulted in wins. Her last appearance was last week when the Chiefs beat the Los Angeles Chargers.

Kelce wasn't able to keep up his big season without Swift in the crowd. The tight end has noticeably had better stats when the pop star's been in-person to watch the game. Against the Chargers, Kelce had a dominant game with 12 passes for 179 yards and a touchdown, and even Kelce has learned about his uptick in performance with Swift there.

The results have been so noticeable that Chiefs head coach Andy Reid is down for Swift to come to any and all games.

"Taylor can stay around all she wants," Reid said.

Swift headed to Arrowhead Stadium in Kansas City, Missouri, last Sunday to cheer on Kelce during the Chiefs' game against the Los Angeles Chargers.

The "Karma" singer was spotted wearing a festive, red Chiefs sweater and a bracelet featuring Kelce's team number 87 for her game-day attire.

Swift was also seen sitting — and dancing — alongside Brittany Mahomes, wife of Chiefs quarterback Patrick Mahomes, during the game's first quarter. In a moment of excitement following the Chiefs' first touchdown, the pair teamed up for a celebratory handshake.
