Watch Taylor Swift and Travis Kelce jam to this rocking love song at the US Open

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

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

Cameras captured Swift rocking sunglasses and a red-and-white checked summer dress as she belted out the lyrics to the British rock band’s 2003 song midway through the match.

Sometimes she would touch and look at her boyfriend, who wore a Gucci bucket hat and cardigan for the occasion.

“I believe in something called love, just listen to the rhythm of my heart. There’s a chance we can make it now, we’ll rock ’til the sun goes down. I believe in something called love,” the two sang.

One social media clip shows Kelce throwing up the sign of the horns while Swift pulls out an air guitar in a separate video.

Swift previously rocked out to the song, which is from The Darkness’ debut album ‘Permission to Land’.

The pop superstar delivered the song’s lyrics while dancing “like no one’s watching” in a 2016 ad for Apple Music.

Frontman Justin Hawkins, in response to the ad: told Billboard that he felt the song “couldn’t 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.

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

Swift is currently on break from the Eras Tour and is in New York ahead of this week’s MTV Video Music Awards, where she is leading artists with 12 nominations.
