Taylor Swift brought out Florence Welch for a stunning duet of “Florida!!!” during the first Eras stop in Miami on Friday.

The night was filled with memorable costume changes, notably a new Reputation bodysuit (the only costume she hadn’t swapped since launching the tour) and an updated blue dress for her Fearless set, sparking speculation that she would be announcing a new Taylor’s Version album soon.

During the surprise performance on Friday, the Florence + The Machine singer joined Swift during the second verse of the TTPD single as the thousands of fans gathered in Hard Rock Stadium sang along.

This is the second time Swift and Welch have performed “Florida!!!” live. In August, the pair debuted the track to close out the final night of the European leg of the trek. That evening also saw super producer Jack Antonoff and Swift strum acoustic guitars to Reputation‘s “Getaway Car,” with Swift later trading her guitar for a piano to debut “So Long, London.”

Earlier on Friday, Swift celebrated the return of her tour — her first show since August — to the States by sharing a video of herself walking into the Miami Dolphins stadium. In a video clip, the pop star wore a yellow sweatshirt and light-washed jeans — while holding her cat, Olivia Benson — as GloRilla and Sexyy Red’s “Whatchu Kno About Me” played. Swift captioned the post, “Back in the office…” and hashtagged it with “#MiamiTSTheErasTour.”
