Katy Perry has posted a couple of well-timed tweets amid a Twitter rant involving Calvin Harris and Taylor Swift.

On Wednesday, Harris embarked on a rant after representatives for his former girlfriend confirmed she had written lyrics for his new song “This is What You Came For” under a pseudonym. While Harris also confirmed Swift was a writer on the song, he also claimed she initially wanted her songwriting credit kept a secret and accused the “Trouble” singer and her team of going “so far out of their way to try and make him look bad”.

After suggesting she should focus on her “new relationship” with actor Tom Hiddleston Harris fired off another tweet: “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.”

Perry, who is the most followed person on Twitter, let her 90 million followers come to their own conclusions by tweeting a gif of her endorsed presidential candidate Hillary Clinton and re-tweeting an old tweet of hers.

Swift and Perry have been the source of fascination of fans for many years due to rumours of a long-running feud. Swift’s 2015 hit song "Bad Blood "was widely rumoured to be about Perry after Swift said in an interview it was about the fallout from a friendship with another female artist, although later distanced herself from those remarks claiming she only said it was about another artist to detract it being about an ex-boyfriend. The video for the single, which depicts Swift complete with all-star squad (including Cara Delevingne, Cindy Crawford and Gigi Hadid) training for a battle with another woman, only served to fuel rumours.

Months later when Swift and Nicki Minaj got into a now infamous Twitter row after she perceived a tweet from Minaj to be aimed at her. When Swift said it was unlike the rapper to “pit women against each other” (which she later apologised for), Perry was quick to chime in: “Finding it ironic to parade the pit women against other women argument about as one unmeasurably capitalise on the take down of a woman…” she wrote on Twitter.

Representatives for Swift and Perry did not immediately respond to a request for comment.
