Taylor Swift brought along surprise guest (and former Eras Tour opening act) Sabrina Carpenter during the Surprise Songs portion of her New Orleans concert on Saturday night.

“I think tonight I'm going to do something different, I'm going to sing a song that's not mine but it's someone I really love so I'm going to see how loud you can sing the song,” Swift told the Audience. “It stuck in my head and it would do me good to know that 65,000 other people have this song in their head the same way I do.”

Swift then began on acoustic guitar with a few lines from Carpenter's “Espresso” before pausing and going into a “tangent.” “I love my friend and I'm just so proud of Sabrina,” Swift said.

She then pulled out a cell phone and called Carpenter live on stage, putting the call on speaker. “I'm actually performing in New Orleans… I just want to tell you that I sang a little bit of 'Espresso' and they all sang so loud,” Swift told Carpenter, who then revealed that she was also at Caesars Superdome.

After a brief conversation, Carpenter then took the stage, where she shared a mash-up of “Espresso” with Swift, followed by 1989 (Taylor's version)“Is It Over Now?” and Carpenter’s hit “Please Please Please.”

Carpenter – who attended the New Orleans gig between stops on her own Short n Sweet Tour; She played in Tampa on Friday and appears in Houston on Sunday – previously serving as the opener of the Eras Tour in late 2023 (during the Latin American leg) and early 2024 (on the Australia and Singapore stops) before returning in the summer with “Espresso “celebrated her breakthrough.”

The two singers previously appeared on stage together on February 23, 2024, when Carpenter also performed for a mix of “White Horse” and “Coney Island” during the “Surprise Songs” portion.
