Yankees manager Aaron Boone teased the couple's arrival prior to Game 1, saying he had heard the two would be in attendance. He also added he has tickets for Swift's Toronto show.

The pop superstar and the Kansas City Chiefs tight end were spotted sitting next to each other in a suite.

Kelce, whose Chiefs are on a bye this week, grew up in Cleveland Heights, Ohio, and is a fan of the area's sports teams. He threw the first pitch before a Guardians game in April 2023, spiking the baseball from the mound. Swift has a baseball history of her own as she performed the national anthem before Game 3 of the 2008 World Series.

Swift and Kelce were spotted at various New York restaurants over the weekend, including a dinner with Blake Lively and Ryan Reynolds on Friday.

The two are no strangers to attending sporting events together in New York. Swift and Kelce took in the men's singles US Open final alongside Patrick Mahomes and his wife, Brittany, in September.

The Grammy-winning artist has been at all three of Kelce's home games this season -- most recently a Monday night matchup against the New Orleans Saints.
