LONDON — Following an electric performance of “Florida!!!” by Florence Welch along with Taylor Swift, the Eras Tour icon surprised everyone by bringing another special guest on stage during the Tuesday concert at Wembley Stadium.

“I think this marks our 131st show on this tour,” Swift remarked while donning a tangerine dress. “It’s an incredible number, and each show features so many unique acoustic performances. I’m always looking to add something fresh.”

She teased the crowd about revealing the surprise guest.

“When I think about how fortunate I am to have the opportunity to perform in the Eras Tour, it’s because over the years, I’ve built meaningful friendships that have helped me along the way,” she shared. The audience began chanting for Jack, who had been seen leaving the stage earlier that evening.

“And I get to collaborate with one of my closest friends,” she introduced Jack Antonoff as he joined her on stage.

“Let’s perform a few tracks that Jack and I both love,” Swift said before kicking off “Death By a Thousand Cuts” from the album “Lover.”

“Should we give it a go?” she asked Antonoff, who enthusiastically responded, “Yes, I really want to.”

This playful moment referenced their song “Getaway Car” from “Reputation,” while the crowd’s wristbands lit up in green.

“I think the audience deserves this,” Swift stated before singing, “No, nothin’ good starts in a getaway car.”

As they approached the bridge, they recreated a viral moment from when they wrote the song, singing, “Put the money in a bag and I stole the keys / That was the last time you ever saw me (oh!).”

As they finished their medley, the two held up their guitars with one hand while embracing each other with the other.

“Giving it up for London’s finest, Jack Antonoff,” said Swift as Antonoff made his way off stage, moving towards the back of the diamond to exit down the platform.

‘So Long, London’

“In London, you know we’ve performed a lot on this tour, and it’s pretty rare for me to have a song I’ve never done before yet here we are,” she stated as she played a floral-patterned piano.

Fans speculated she might perform “So Long London” from “The Tortured Poets Department” during her final Wembley performance. And she did. Swift still has seven songs left to sing from her eleven studio albums.

She didn’t announce “Reputation (Taylor’s Version)” as fans had expected.
