Taylor Swift and her boyfriend attended the US Open final. What song did they rock out to?

Yesterday, the final of the last Grand Slam tournament of the season, the 2024 US Open, took place in New York. Jannik Sinner triumphed over American Taylor Fritz in straight sets.

For Fritz, this marked his first-ever appearance in a Grand Slam final.

Details: One of the match's highlights was the appearance of the USA's most talked-about celebrity couple—singer Taylor Swift and NFL Kansas City Chiefs star Travis Kelce.

They came to support Fritz, but their presence wasn't enough to help him overcome the world No. 1. A video of Swift and Kelce singing "I Believe in a Thing Called Love" together went viral online.

Reminder: Recently, the NFL released a season promo that sparked fan outrage due to the prominent number of Taylor Swift references.
