The country singer and the British singer join forces to perform their collaboration track, 'Everything Has Changed'.
Earlier this year, Ed Sheeran served as an opening act for Taylor Swift's "Red" tour. Now, the country/pop star returned the favor by appearing on the British singer's concert at Madison Square Garden in New York earlier this week.
"I've traveled all over the country and I've seen some wonderful things and I owe it all to someone," Sheeran said when introducing his "good friend" onto the stage. Swift then came out wearing an "I Love Ed" t-shirt and a black hat.
They played their own guitar while leading the crowd to sing along to "Everything Has Changed", the two singer's collaboration that is featured in Swift's "Red" album.
Sheeran later thanked Swift for coming to his concert and performing together. He posted an Instagram photo of him posing with the "I Knew You Were Trouble" hitmaker and captioned it, "Thank you to ms. Swift for being the surprise guest this evening!"
That night's show marked Sheeran's second headlining concert at Madison Square Garden. Previously, he graced the stage of the iconic venue on Tuesday, October 29 and treated fans with a new song whose title hasn't yet been confirmed. The 22-year-old gingerhead's concert at MSG continues on November 7.
