Right I don't know if any of you lot know hence why I'm about to ask this but all the time I see monsters and katy kats hating on each other / each other's artist all the time..

What is the reason for this? Did some massive fued happen back in late 2000's which I missed

each fan base always attacks each other all the time lol

So I want to know why do each fanbase hate each other????

Debuted at similar times, Monsters dragged Katy and the Kats to the PITS during the TD/CDT era and then Roar vs Applause happened.

Katy has, on multiple occasions, made shady remarks directed at Gaga since 2010. She's also praised her a few times on Twitter, dating back to 2009. But since then she's kept her distance. Pretty much like Gaga's obsessed ex-stans on ATRL.

Gaga on the other hand has defended Katy during this said 'feud' for a number of years, saying she doesn't support it, and only recently made one shady remark towards Katy (artRave) after the years and years of comparisons between the two.

Katy's fans think it's about success, which couldn't be further from the truth. No one likes a rude, bitter and jealous woman.

In b4 lock.
