Taylor Swift and Sabrina Carpenter Debut ‘Espresso (Taylor’s Version)’ at the Eras Tour

Yes, even Taylor Swift has “Espresso” stuck in her head.

On the second night of her New Orleans Eras Tour, Swift ignored continued calls for a Reputation (TV) announcement, but delivered something unexpected in its stead. During the acoustic portion of the night, she pulled out a surprise song no one could have predicted because it’s literally not in her discography.

“I’m gonna sing a song that’s not mine, but it’s somebody that I really love,” she told the crowd, per one TikTok video shared by @lovelisapizzy. “It’s been stuck in my head, and I just it would make me feel good if I knew 65,000 other people had the sun stuck in their head, just like I do.”

From there, she went into the first verse of “Espresso” by Sabrina Carpenter, who previously opened for the pop star during the Latin America leg of the Eras Tour, as well as some other international stops. After remarking on how “proud” she is of her friend’s rapid rise to the top of the charts, Swift decided to give the singer a call on the phone. Of course, it was a bit hard to hear their conversation because of all the screaming. Don’t worry, Swift shushed the crowd multiple times, which online fans found “so unserious.”

“Is there any chance you could get off the roller coaster you’re on and, like, put on some clothes and just like, come down the stadium?” Swift asked Carpenter, per one particularly clear video shared by @lxv.swift13. “Ballpark, how long did that take you?” Carpenter’s response: Five seconds.
