Unless you've been spent the last week hiding from the Internet for fear of hearing anything negative about your beloved Duggars, you've probably encountered Taylor Swift's "Bad Blood" video.
The clip, which features Swifty and several of her famous friends rocking $13,000 in sex shop clothes went mega-viral for obvious reasons and now has nearly 90 million views on YouTube.
Unfortunately, not everyone was a fan of Taylor's badass antics.
We learned several months ago that "Bad Blood" was written about Taylor's feud with Katy Perry, and we're guessing KP was none too thrilled to see the song has become a massive success as a single.
So perhaps it's not surprising that Katy is penning her own response with the help of John Mayer, who's something of an expert (Read: "has slept with") both girls.
“Katy thinks revenge is a dish best served cold," a source tells Heat magazine.
"She’s even more determined to show people what she calls ‘the real Taylor,’ she’s writing some big, anthemic-type songs that’ll feature dirt on Taylor that John’s told her from when they used to date.”
Katy and John are back together for the moment (We give it a week.), and while most of her fans thought the reconciliation was a bad move for Katy, it might be well worth if it means delivering a crippling, radio-friendly blow to her arch rival.
Yes, we've got a full-blown pop diva feud going on, and Mayer has positioned himself squarely in the middle. We're sure it's only a matter of time before he proposes the idea of getting in between Katy and Taylor in another way.
