Gracie Abrams is known and loved by Swifties everywhere for her opening support spot on Taylor Swift’s The Eras Tour.

TayTay returns the favor on the collaborative new single “Us,” which dropped at the stroke of midnight along with the rest of Abrams’ new album The Secret of Us.

Abrams and Swift co-wrote “Us,” the crown jewel of Abrams’ 13-track sophomore studio LP, with musical input from producer, collaborator and mutual friend Aaron Dessner of the National.

“Us” is an anthemic folk number, with a polished pop production. And it’s unmistakably the work of TayTay.

On it, Abrams and Swift sing, “I know you know/ It felt like somethin’ old / It felt like somethin’ holy, like souls bleedin’ / So, it fеlt like what I’ve known/ You’re twеnty-nine years old / So how can you be cold when I open my home?”

“It was just really fun to watch the chemistry of Gracie and Taylor bouncing off each other,” Dessner tells Billboard, “Gracie in total wonder and awe watching how Taylor records and produces her vocal performances and builds the world.” Stream “Us” below.

The 24-year-old Abrams spent the summer opening for Swift’s The Eras Tour, a role she’ll reprise on select dates in North America later this fall. She’ll head out on her very own headlining tour of theater-sized venues across the United States, starting Sept. 5 in Portland.

“Taylor’s brilliant at synthesizing a whole story,” Dessner continues over his Zoom with Billboard. “Us” just “brought everything” about Gracie’s album “into focus in a beautiful way.”

The Secret of Us features the previously-released tracks “Risk” and “Close to You,” which debuted at No. 49 on the Billboard Hot 100 chart, and it’s the followup to Abrams’ debut record Good Riddance, which arrived February 2023, peaking at No. 52 on the Billboard 200.
