If you somehow thought that ancient feud between Katy Perry and Taylor Swift was over, then you have been sorely mistaken.
Not only is it still going, but it just got personal.
We only just got wind that Katy Perry's new album will feature a response to Taylor's diss track "Bad Blood", but now, Katy is teaming up with Taylor's ex-boyfriend Calvin Harris.
Oh my word.
Yesterday Calvin posted a teaser for his new album, Funk Wav Bounces Vol. 1, on Twitter and Instagram, and unsurprisingly, it features a lot of collaborations, such as Ariana Grande, Nicki Minaj and Pharell Williams... oh, and KATY FREAKIN' PERRY!!!
It's pretty shady considering how awful their break-up ended up being, and we all know the drama between Katy and Taylor.
Katy recently told EW in an interview that, "One thing to note is: You can't mistake kindness for weakness and don't come for me. Honestly, when women come together and they decide to unite, this world is going to be a better place. Period end of story. But, let me say this: Everything has a reaction or a consequence so don't forget about that, OK, honey."
Fans are naturally losing their marbles online.
His album is set to drop on June 30... so the question is, are you keen? Or TERRIFIED?
