Just when the world was coming to terms (sort of) with Taylor Swift and Tom Hiddleston’s new relationship, and Calvin Harris had seemingly moved on, the Scottish DJ just went and reignited the fire.
Harris has gone on a twitter rant, addressing reports that Swift wrote his latest song This Is What You Came For.
Tay’s team ended up confirming the story to People which has been circling for some time, saying: "Taylor Swift wrote "This Is What You Came For" under the pseudonym Nils Sjoberg."
While at first, Calvin seemed content with leaving it there, tweeting, "And she sings on a little bit of it too… Amazing lyric writer and she smashed it as usual".
He then seemed to have a change of heart after a report from TMZ claimed that Swift "wrote the song, sat down at a piano and did a demo into her iPhone."
And that’s where it all goes downhill.
He then brought Katy Perry into the fray, knowing full well there’s no love lost between the pair.
While Katy didn’t directly comment, she posted a rather telling gif in response.
