In the fan-captured video (embedded above), Swift asks her captive audience, “So I was wondering if an audience this incredible might be up for a surprise performance, what do you think?” She holds up her mic to receive screams of affirmation and then she called up somebody who’s played Wembley “bunches of times” before asking, “London, would you be excited if I told you Niall Horan is here?”
The former One Direction member slowly approaches Swift as the crowd roars and the first beats of “Slow Hands” play. He kicks off the sultry, UK Singles Chart Top 10 hit by singing the first verse as he continues to walk towards Swift. She smiles, advances towards him and then they circle each other. The “End Game” singer joins in on the chorus and takes over vocals for the second verse. They both engage the clamoring audience, as a sea of swaying cell phone lights fill the stadium.
