You're probably aware that the Taylor Swift-Katy Perry feud has been going on for quite some time now, but this week, things got real like never before.
The beef may have started over a dude (Katy and Taylor both banged John Mayer.), but KP raised the stakes this week by coming after something far more near and dear to Taylor's heart than any guy.
That's right - Katy has set her sights on Taylor's chick clique.
The photo above shows Tayor besties (or maybe we should say "former Taylor besties") Lorde and Ellie Goulding partying at the Cahateau Marmont with none other than She-Who-Must-Not-Be-Named.
Adding to the scandalous nature of the pic is the fact that it was first posted online by Goulding, who deleted it the next day.
When asked why she removed the photo from her social media pages, Goulding offered a lame excuse about how she didn't like the way she looked in it.
Normally, we'd say that's a fair reason to take down a photo, but in this case, it had already been reposted by Lorde, Katy and about a million other people.
Between this and the revelation that Gigi Hadid is dating Joe Jonas, it's been a day of betrayal for Taylor.
Soon, heads will roll! Then, a song will be written about it!
