Taylor Swift invited Sabrina Carpenter onto the stage during last night’s Eras Tour show. Check out the footage below.

Swift was performing at New Orleans’ Caesars Superdome on Saturday (October 26) when she told fans she was going to do something different for the acoustic section by singing someone else’s song.

“It’s been stuck in my head,” she told the crowd, before beginning to sing Carpenter’s huge hit single ‘Espresso’. After playing for a few seconds, she paused and asked fans: “Is it OK if I call her, and you guys can say hi?”, and then picked up the phone and dialled Carpenter’s number.

Swift then put the ‘Taste‘ singer on speakerphone and asked her how long it might take her to get to the stadium. Moments later, Carpenter walked on stage.

They performed a mashup of ‘Espresso’, Swift’s ‘1989’ vault track ‘Is It Over Now?’ and another one of Carpenter’s big hits, ‘Please Please Please’.
