Hmm... Where have we heard this before...
It's gotta be so hard when two of your fabulous, fun girlfriends are feuding!
And while Taylor threw down the gauntlet by calling out another musical lady for trying to sabotage her tour, Katy retaliated with a Twitter message obviously directed at Swifty. Now, Lorde just has to be torn up over the divide.
Yup, that's Katy partying it up with Lorde.
We just have to wonder if Tay ever saw this pic from way back in February. Well, if not, maybe she saw Ellie's #TBT of it.
But we hope all the feuding does't mean Lorde is gonna have to pick a side!
