|Marina and the Diamonds & Charli XCX|
|Released||May 1, 2013|
|Writer||Marina Diamandis, Charlotte Aitchison|
The song, probably recorded in 2011 or 2012, was originally a solo song by Diamandis entitled "The Other Foot". The demo did not make the cut for Electra Heart, but was leaked on June 3, 2012.
The song was updated in early 2013 with new material from Charli XCX. Two slightly different versions of the duet exist, one uploaded (then quickly deleted) by Charli XCX, and the final version uploaded a few hours later by both artists. Fans speculated that the two would perform the song together on the North American leg of The Lonely Hearts Club Tour, but this never occurred.
