Katy started it, then she pretended to play nice. I like some of her songs, but she is your typical fake high school classmate

A feud no one cares about, no once mentioned in the media, monsters, gaga and kats need a life, especially the former 2, being angry at an opinion said 5 years ago and create a one sided war just shows how petty and unhappy with life you guys are

It was a fan feud.

Katy and Gaga may be a little salty toward one another and Roar vs Applause was a thing...but it wasn't really a mainstream feud.
