Watch Taylor Swift And Travis Kelce Jam Out To This Rockin' Love Song At The U.S. Open

Taylor Swift and Travis Kelce ’s hearts were on overdrive Sunday as they sang along to The Darkness ’ “I Believe in a Thing Called Love” while attending the men’s singles final at the U.S. Open .

The pop superstar and Kansas City Chiefs star, who were seen at the match with quarterback Patrick Mahomes and his wife Brittany Mahomes, watched from the stands at Arthur Ashe Stadium as Jannik Sinner beat Taylor Fritz to win the major title.

Cameras caught Swift rocking shades and a red-and-white checkered sundress as she belted out the lyrics to the British rock band’s 2003 track mid-match.

At times, she touched and locked eyes with her boyfriend, who donned a Gucci bucket hat and a cardigan to the occasion.

“I believe in a thing called love, just listen to the rhythm of my heart. There’s a chance we could make it now, we’ll be rocking till the sun goes down. I believe in a thing called love,” the two sang.

One clip on social media shows Kelce tossing up the sign of the horns while Swift, in a separate video , is seen breaking out an air guitar.

Swift has previously rocked out to the song, which stems from The Darkness’ debut album “Permission to Land.”

In a 2016 ad for Apple Music, the pop superstar mouthed the lyrics to the song as she danced “like no one’s watching.”

The Darkness singer Justin Hawkins, in response to the ad, told Billboard that he didn’t think the track “could get any sexier, but somehow Taylor raised the bar.”

Hawkins added that Swift was a fan of the British rockers and used to attend their concerts “back in the day.”

“It’s good to see she hasn’t given up on her roots! Take it to the bridge, Swiftmeisteress!” he said of the ad.

Swift is currently on break from her Eras Tour and in New York ahead of this week’s MTV Video Music Awards , where she leads artists with 10 nominations .
