(KRON) — Taylor Swift walked into the Super Bowl flanked by actress Blake Lively and rapper Ice Spice. She was not wearing her boyfriend’s No. 87 or her lucky No. 13.

Instead, the international superstar’s jacket had No. 60 on the back. Why might that be?

One possible explanation is that the Kansas City Chiefs’ first season of football was played in 1960. At the time, they were called the Dallas Texans, as owner Lamar Hunt started the team in the town where he went to college (Southern Methodist University). They relocated to Kansas City for the 1963 season.

Swift’s jacket appears to be part of NFL reporter Erin Andrews’ fashion collection. It is going for $129.99 on Fanatics.

Swift flew in from Tokyo to watch her boyfriend, Chiefs tight end Travis Kelce, go against the San Francisco 49ers for his third Super Bowl ring.

Swift and her entourage are sitting in a suite courtesy of Kansas City Chiefs tight end Travis Kelce, whom she has been dating since the first few weeks of the NFL season.

Kelce reportedly purchased the suite, which cost more than $1 million, sources told TMZ.
