Taylor Swift has had quite a few surprises during her Eras Tour and that was also evident during her first show today at Wembley Stadium in London. Ed Sheeran was the surprise of the evening and performed a medley of their collaborations.

The two performed their duets "Everything Has Changed" and "End Game" during the surprise portion of the first of five London shows. About halfway through "Everything," which was included on her 2012 album "Red," Sheeran rose from behind the stage and joined Swift for the song before segueing into "End Game," their duet from 2017's "Reputation." The pair wrapped with a rendition of Sheeran's "Thinking Out Loud" before embracing and Swift celebrating their friendship.
