Eagle-eyed fans of Taylor Swift have zeroed in on her mom, Andrea Swift, and a charm on the purse of the mother of the ‘Anti-Hero’ singer as the reason the Kansas City Chiefs keep winning.

The Chiefs improved to 9-0 on Sunday with a 16-14 win over the Denver Broncos, needing to block a field goal as time expired to not lose for the first time since last Christmas.

Attending the game was a trio of Swifts, Taylor, Andrea, and dad Scott Swift, to watch Travis Kelce play at Arrowhead Stadium.

Andrea carried a red-and-yellow No 87 charm on her purse, in tribute to her daughter’s longtime boyfriend’s jersey number.

Swift’s fans are convinced its part of the reason the Chiefs can’t stop winning after flirting with losses throughout the season.

‘It just might be that this charm carries more weight than we think,’ one fan of the 14-time Grammy Award winner said.

Swift has attended every Chiefs home game this season, with the team holding a 5-0 record this season with her in a luxury suite at Arrowhead Stadium.

The Chiefs have a 14-3 overall record with Swift in attendance, dating back to her first appearance as Kelce’s girlfriend last September during a game against the Chicago Bears.

The final leg of the ‘Eras Tour’ starts Thursday in Toronto, with Swift likely making her way to Canada shortly after the final whistle.

The Swift trio got to witness Kelce score his first touchdown at Arrowhead this season with a crucial fourth-down grab.

The Chiefs may face the toughest test of their season so far next week, going on the road to face the Buffalo Bills.
