Pop superstar Taylor Swift was reported to have secretly attended the Kansas City Chiefs' game against the Baltimore Ravens at Arrowhead Stadium in support of her fiancé, Chiefs tight end Travis Kelce, on Sunday (September 28).

Swift, 35, was not seen on CBS Sports' broadcast Sunday, but reportedly made a quiet entrance as she had done for the Chiefs' home opener two weekends prior, PEOPLE reports. The singer's father, Scott, and brother, Austin, were spotted at Arrowhead Stadium alongside Kelce's mother, Donna, during Kansas City's 37-20 win.

Swift made the secret appearance at Arrowhead Stadium hours after attending the wedding of her longtime friend, fellow pop star Selena Gomez, and producer Benny Blanco, in Santa Barbara, California, where she reportedly gave a heartfelt speech at the reception, according to PEOPLE. The Chiefs earned their second victory of the 2025 NFL season on Sunday, having previously defeated the New York Giants during their Week 3 Sunday Night Football matchup following a disappointing 0-2 start.

A video shared online previously showed Swift walking behind a sliding divider that was wheeled from one door to another during her previous appearance at Arrowhead Stadium for the Chiefs' loss to the defending Super Bowl champion Philadelphia Eagles in Week 2. The singer announced her engagement in a joint Instagram post with Kelce featuring several photos of the proposal shared on August 26.

"Your English teacher and your gym teacher are getting married," she wrote in the caption of the post, which has more than 37 million likes as of Wednesday.

The engagement reportedly took place two weeks prior at a garden at Kelce's home in Lee's Summit, Missouri, his father, Ed, told ABC News 5.
