While there have been rumors that the two are ready to put their differences aside at the MTV Video Music Awards this Sunday -- which Perry is hosting -- the producer behind this year's VMAs, Garrett English, told ET on Wednesday that it's "not happening."
But Swift had everyone talking ahead of the release of her GRAMMY-winning 1989 album, thanks to her quotes to the music magazine, in which she revealed she had a feud with a fellow pop star, which inspired her hit, "Bad Blood."
Perry didn't shy away from Swift's Rolling Stone comments, tweeting the next day, "Watch out for the Regina George in sheep's clothing..."
Her performance of "Bad Blood" curiously featured a cameo from a life-sized shark mascot -- a not-so-thinly veiled dig at Perry's Super Bowl dancer-turned-internet meme.
Perry made it clear she was ready to make amends with Swift during a conversation with Arianna Huffington in June, which was live streamed to promote Witness.
