The bad blood boils again!

Now that what initially seemed like an amicable split between Taylor Swift and Calvin Harris has descended into an open feud between the exes, with Harris name-checking Swift's alleged enemy, Katy Perry, in a new tweetstorm on Wednesday, Perry slyly tweeted out a GIF of presumptive Democratic presidential nominee Hillary Clinton shooting out a sort of 'I told you so'-look shortly afterward. While not addressing all the unfolding drama in words, it nevertheless seemed to get across everything there is to say.

You have to give it up to Perry for being able to convey so much with so little. As if that wasn't enough, Katy also retweeted her own tweet from last year, where she wrote, "Time, the ultimate truth teller."

Guys, pop music is having it OUT rn.

The shade hearkens back to the last time the "Roar" singer threw down the social media gauntlet against Swift. In 2014, she referenced Mean Girls when she tweeted, "Watch out for the Regina George in sheep's clothing..."

Perry would later confirm the (in?)famous tweet was in response to Swift's Rolling Stone interview, where she accused Perry of trying to "sabotage an entire arena tour."

"If somebody is trying to defame my character, you're going to hear about it," Perry, 30, explained.

Now, the rift that had evidently been brewing between Swift and Harris ever since she has started seeing Thor actor Tom Hiddleston, came to a breaking point after Swift's rep confirmed to ET on Wednesday that the 26-year-old singer wrote Harris and Rihanna's summer hit, "This Is What You Came For," under the pseudonym Nils Sjoberg.

Calvin clapped back on Twitter, writing, "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."

The 32-year-old producer then threw Perry's name into the mix, adding, "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."

And while we are big fans of love and friendship, we can't help but anticipate the shaaaady fall/winter music season that's gonna come of this.
