June 21 (UPI) — Gracie Abrams and Taylor Swift team up on a new song featured on Abrams’ album The Secret of Us, released Friday.

Swift, 34, joins Abrams, 24, on the song “Us,” one of the 13 tracks on the new album.

In “Us,” Abrams and Swift question an ex after the end of a relationship.

“Do you miss us, us? / I felt it, you held it, do you miss us, us? / Wonder if you regret the secret of us, us,” the pair sing.

Abrams shared videos Friday on Instagram that show herself and Swift writing the song and dealing with a small kitchen fire.

“Writing this entire song from 2am to 6am was some of the most fun I’ve ever had in my life. @taylorswift now we know how to use a fire extinguisher. I love you,” Abrams captioned the post.

The Secret of Us also features the tracks “Felt Good About You,” “Risk,” “Blowing Smoke,” “I Love You, I’m Sorry,” “Let It Happen,” “Tough Love,” “I Knew It, I Know You,” “Gave You I Gave You I,” “Normal Thing,” “Good Luck Charlie,” “Free Now” and “Close to You.”

Abrams performed “Risk” during an episode of The Tonight Show starring Jimmy Fallon in May. She also discussed opening for Swift on the pop star’s Eras tour in 2023.

“I mean, it was the craziest privilege,” she said of performing on Swift’s tour. “We all love her dearly. It’s a real master class to watch, to watch her do what she does.”

Swift is in the midst of her Eras tour and will next perform Friday in London. The singer released her album The Tortured Poets Department in April.
