July 13: Taylor's rep confirmed exclusively to People that Calvin's hit, "This Is What You Came For," was actually written by Taylor under the pseudonym Nils Sjoberg. After the news broke, Calvin once again took to Twitter to deny the claims in a series of tweets, writing, "I wrote the music, produced the song, arranged it and cut the vocals though. And initially she wanted it kept secret, hence the pseudonym," adding, "Hurtful to me at this point that her and her team would go so far out of their way to try and make ME look bad at this stage though . . . I know you're off tour and you need someone new to try and bury like Katy ETC but I'm not that guy, sorry. I won't allow it." Katy, of course, caught wind of Calvin's claims and responded by posting a GIF of Hillary Clinton looking rather satisfied, which she then followed up with a retweet of an old tweet from a year ago that read, "Time, the ultimate truth teller."
While Taylor has yet to respond, she did step out in Australia looking calm and carefree, just a day later.
