Taylor Swift and Sabrina Carpenter made crowd go crazy at the 'Eras Tour'

The 'Eras Tour' has definitely been an absolute success. Taylor Swift's magic and performance are the perfect combination for an experience any music fan will love. At every concert and every show, she gives her fans her 100%. That's one reason her 'Eras Tour' is shaping up to be truly historic in the music industry.

Swift is passionate about making every moment legendary, and in an epic city like New Orleans, she didn't hold back. She even brought another incredible artist, Sabrina Carpenter, to the stage as a special guest.

The two have known each other for a long time, and they seized this opportunity to wow both fan bases with a surprise collaboration on Carpenter's song, "Espresso."

How did they make it happen?

It all started when Swift asked the crowd for a phone to call her former Eras Tour opening act, Sabrina Carpenter. She told the audience to stay silent as she put Carpenter on speaker.

When Carpenter answered, Swift shared, "I just sang your part in 'Espresso,' and the crowd sang every word so loud!"

Swift then playfully asked, "Why aren't you here with us?"

Carpenter replied that she was somewhere where people were "screaming really loud" too.

"How long would it take you to get here?" Swift asked. Carpenter answered, "It would probably take me, like, five seconds," sending the crowd into a frenzy.

The two singers then surprised fans with a mashup of Carpenter's "Espresso" and "Please, Please, Please" with Swift's "Is It Over Now?".
