Emeli Sande has been out of the spotlight for some time, but she popped up onstage recently with Taylor Swift. The country superstar was in London wrapping up her RED tour when she surprised the audience with a special guest.

Sande appeared to perform her anthemic ballad 'Next to Me,' off her album, 'Our Version of Events,' with Swift at London’s 02 Arena Monday night (Feb. 10). Dressed in a lacy black mini-dress with matching boots, the singer-songwriter had the sold-out crowd singing along to her infectious lyrics.

During Sande’s performance, Swift can be seen doing some sort of jitterbug dance move, which looked awkward at times. She also sang a few lines from the song as well.

Afterward, Swift went on Twitter to thank Sande for her London appearance. "SHE IS SO HEAVENLY. I've had the best time here," she tweeted.

During her U.K. tour, Swift welcomed plenty of surprise guests to the stage including Jennifer Lopez and Carly Simon.
