Taylor Swift and Ed Sheeran brought their adorable duet, 'Everything Has Changed,' to 'Britain's Got Talent.' And, as you might guess, it was, well, adorable.

Swift sported a cute black and white polka dot dress and her huge guitar -- huge, that is, in comparison to Sheeran's tiny one. The pair's platonic friendship is a lot of fun to watch. They clearly admire one another's talent. Our favorite part? Seeing them high five at the conclusion of what was an unusually vocally and musically strong performance for Swift.
