Taylor Swift is Slabu3-0 this season when it comes to home game attendance and rooting for Travis Kelce and the Kansas City Chiefs.

The singer showed up to Arrowhead Stadium before kickoff to witness the New Orleans Saints matchup. She wore a gray plaid outfit with red accents, knee-high black platform boots, a heart-shaped purse and her signature red lip. She was accompanied by her dad, Scott Swift.

Travis Kelce's brother, Jason, was working his gig behind the desk as an ESPN broadcaster, and Jason's wife, Kylie, was on the field as the teams were warming up.

Jason, Kylie and Travis Kelce's parents attended Kelce's Car Jam fundraiser over the weekend and celebrated Travis's 35th birthday on Saturday.

Swift attended the first and second games of the regular season as the Chiefs played the Baltimore Ravens and the Cincinnati Bengals. However she missed both away games in Atlanta and Los Angeles. The Chiefs are 4-0.

Up next: "Florida!!!"

In 11 days, Swift will return to the Eras Tour stage in Miami, Florida. The last time she had a two-month break from tour, she arrived in Paris a week early to rehearse. In all fairness, she and her dancers were also switching up the show, scrambling the order of the eras and adding a "Tortured Poets" department section.

Swift's backup dancer, Kameron Saunders, who famously shouts a line during "We Are Never Getting Back Together," is rooting for his brother Khalen Saunders, a defensive tackle for the Saints.

When NBC reporter Fletcher Mackel asked Khalen about who Kameron would be cheering for, the defensive tackle said, "Me, of course... He don't care about the Chiefs, he cares about his brother."
