Ed Sheeran and Taylor Swift have been spending quite a bit of time together lately, and at her show in Berlin Friday her Brit buddy made a guest appearance.

"Berlin you were a DREAM!! AND @edsheeran came along to surprise you with 'I See Fire.' Thank you for being wonderful," Taylor tweeted. She also linked a video of the duet performance, the song he wrote for the soundtrack of The Hobbit: The Desolation of Smaug.



Do you think he'll make another appearance at one of Taylor's last two shows at London's O2 arean tonight or tomorrow?
