Taylor Swift is the Queen of Shade when it comes to burning her exes in her songs.
The the pop star was heard sound-checking her ex Calvin Harris’ song This Is What You Came For ahead of her gig this weekend in Austin, Texas, something we can't imagine going down too well with Calv.
The track was released with Rihanna as the vocalist but Taylor recently revealed it was actually her that co-wrote it and performed on it in parts.
This summer it emerged Taylor helped to pen the track under her pseudonym Nils Sjoberg and this was given as an official credit on the record.

Soon after this emerged Nils was swiftly removed from the list of songwriters and Taylor’s real name was put in its place.
Calvin confirmed that he did write the music, produce the track and arrange the vocals but Taylor sang on the track "a little bit", despite wanting to keep this on the down low initially.
He even hailed his ex as an "amazing lyric writer" but things quickly turned sour when Calvin went on a Twitter rant and hit out at Taylor and her team for the "hurtful" way the news she was involved in the record came to surface.
