Taylor Swift surprises her London audience with special guest Ed Sheeran

Taylor Swift continues to surprise her audience as her Eras Tour rolls on and kept them rolling during her first show at London's Wembley Stadium with a surprise appearance from Ed Sheeran for a medley of their collaborations.

The two performed their duets "Everything Has Changed" and "End Game" during the surprise song section of the first of five London shows. About halfway through "Everything," included on her 2012 album "Red," Sheeran rose up from the back of the stage and joined Swift for the song before transitioning to "End Game," the duet from 2017's "Reputation." The pair ended with a rendition of Sheeran's "Thinking Out Loud" before they hugged and Sheeran left the stage.
