Taylor Swift Brings Ed Sheeran Out for ‘Everything Has Changed’ Mash-Up at Wembley Eras Tour Show

Everything has changed for fans at night 1 of Taylor Swift‘s latest run of Wembley Eras Tour shows: The pop star just treated the crowd to a surprise duet with longtime friend and collaborator Ed Sheeran.

As captured by fan video in London, the “Anti-Hero” singer brought out her fellow pop superstar during the surprise song section of her three-hour-plus show Thursday (Aug. 15). Fans went wild as Sheeran came out onstage and the duo hugged, with Swift calling the “Bad Habits” singer her “second brother,” according to tweets from fans.

Swift and Sheeran, who have been close pals for well over a decade, launched into a mash-up of two past collaborations — 2012’s “Everything Has Changed” and 2017’s “End Game” featuring Future — plus the British singer/songwriter’s 2014 solo smash “Thinking Out Loud.” The tracks peaked at Nos. 32, 18 and 2 on the Billboard Hot 100.

“People fall in love in mysterious ways/ Maybe just the touch of a hand,” the sang in harmony as both strummed acoustic guitars, combining lyrics from the three tracks. “All I know is a simple name/ And everything has changed.”

After Sheeran departed the stage, Swift moved on to the next surprise song performance on piano, mashing up “King of My Heart” from Reputation and “The Alchemy” from The Tortured Poets Department. Over the next few days, the “Karma” artist will perform five more shows at Wembley before tying a bow on the European leg of her global Eras trek.
