Taylor Swift has been having fun in London. Earlier this week she brought out singer Sam Smith to perform his debut solo single "Money on My Mind," and today she posted a short video on Instagram of her, Ed Sheeran and British model Cara Delevingne singing an acoustic cover of The Knife's "Heartbeats."
At just over 10 seconds, the video is inherently fleeting, but it wouldn't be surprising if a full version surfaced at some point. As she gears up to work on her fifth album, it's enticing to think of Swift listening to a band as bizarre as the Swedish brother-sister duo, though it's also possible she was influenced by the Jose Gonzalez version of "Heartbeats."
Swift wraps up the international leg of her at The O2 Arena in London on Feb. 11 before (hopefully) returning to America and hopping in the studio.
