Tons of celebrities attended Taylor Swift's Eras Tour throughout its nearly two-year run - and some of them also pop up in her new Disney+ docuseries, Taylor Swift: The End of an Era. The six-part special debuted on Disney+ December 12 and features cameo appearances from Swift's family members as well as some of her more famous pals. In the first episode, for example, the pop star's longtime friend and collaborator Ed Sheeran appears before her London show. When Swift played at London's Wembley Stadium in August 2024, Sheeran joined her during the surprise song portion of the set, and the duo performed two of their duets: "Everything Has Changed" and "End Game." The End of an Era chronicles the latter half of The Eras Tour, which kicked off in Glendale, Arizona, in March 2023. After 149 shows in 51 cities across five continents, Swift wrapped up the tour in Vancouver, Canada, in December 2024. A separate documentary chronicling the last concert, titled The Eras Tour: The Final Show, also dropped on December 12.

Ed Sheeran VALERIE MACON / AFP Swift's longtime friend and collaborator appears in the first episode, meeting her backstage before her first August 2024 London date to briefly rehearse before his surprise appearance later in the evening. When Swift confesses that she felt "hunted" after the Vienna situation, Sheeran offers words of support. "I feel like people have forgotten that, like, you're a human being amongst all of this as well," he tells his friend before they start practicing "Everything Has Changed." Florence Welch MARIA ALEJANDRA CARDONA/AFP via Getty Images Florence + The Machine frontwoman Florence Welch joined Swift on stage for the final London Eras show, and episode 2 reveals how they quickly added "Florida!!!" to the set. Welch, who reveals she had "never done" a stage lift in her career before The Eras Tour, was initially shocked by the scale of her surprise appearance. "I have performed on big stages, but this is not [the same]," Welch admits in a confessional interview. "I thought I'd just show up and I'd run around, because that's what I do at my own shows. I just show up and I just run around. ... When I got there, it was like, 'OK, now this is your choreo.' I was like, 'Oh, no, no, wait, wait, you have me confused, I don't do this. I'm gonna f*** this up.'" Later, Welch explains why she and Swift connect as friends, saying, "We're similar in that the persona is huge but the person is soft, and so I think that's why we get along. Externally, the thing is really big, but when we're together, we're just, like, silly and goofy." Seeing her friend on stage, however, showed Welch the difference between the person she knows in real life and the star. "The feeling of coming up for the first time in that lift, it was kind of like landing on Mars. Because I'd never seen the stage lit up before, the sound of the crowd. That was really extraordinary," Welch recalls. "You see this cultural moment from the outside, and I suddenly was, like, inside of it. It was wild but it was really fun and completely terrifying. Also, Taylor's my friend, and I know her as this, like, very cozy person, and I came out of that lift and I was like, 'Oh, my God, it's f***in' Taylor Swift."
