Swift then dialed Carpenter and put her on speakerphone, asking how long it would take her to get to the stadium.

To the audience's surprise, Carpenter appeared on stage just moments later, and the two stars launched into a fun mashup of "Espresso," Swift's vault track "Is It Over Now?" from 1989, and Carpenter's other hit song "Please Please Please."

One of the standout moments of the night was Swift singing the line, "I'm working late 'cause I'm a singer" from Carpenter's "Espresso," to a sold-out crowd at nearly 11 p.m. Taylor Swift Wardrobe Malfunction: Singer’s Vivienne Westwood Gown Unzips During Miami Concert; Video of Backup Dancers Coming to Her Rescue Goes Viral – WATCH.
