After Katy Perry seemingly responded to Calvin Harris' set of tweets during which he fired off at recent ex Taylor Swift after she accused the DJ of essentially stealing the hit song "This Is What You Came For" from her, fans of the "Fireworks" singer had a little bit more to say.

Immediately after Katy's response, her "KatyCats" trolled the country singer's Instagram account with snake and poop emojis, but Taylor's "Swifties" have since fired back with heart emojis.

As everyone knows, Katy and Taylor have had beef for quite some time — hence the song "Bad Blood" — and this apparently stemmed from Taylor accusing Katy of stealing some of her backup dancers during her tour.

Even more so, Calvin even called out their feud in one of his tweets, writing, "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."

T. Swift has yet to respond to her ex or the singer, but it looks like this girl fight ain't going anywhere!
