I See Fire Duet with Ed Sheeran and Taylor Swift!

Lucky Swifties and Sheerios at the O2 World Arena in Berlin, Germany were in for a big surprise when they witnessed an I See Fire duet performance between Taylor Swift and Ed Sheeran!

10,700 fans were in the audience to watch Taylor Swift perform at the Red Tour's stop in Berlin.

At one point in the show, Taylor started to talk about the new track "I See Fire" by BFF Ed Sheeran, who had joined her on the North American leg of her Red Tour.

Ed surprised the entire audience when he made a surprise appearance from backstage with his acoustic guitar in hand, and the two began a beautiful duet of the song, written specifically to appear in the second Hobbit film.

We absolutely love the way this song sounds with both of the stars' voices working together in harmony, and from the sound of the audience's screams, they enjoyed it too!
