KATY hated GAGA IS REASON WHY send CONGRATULATIONS TO HER ON TWITTER? AND SPEAKING OF HER mention cute things? AND THAT'S IT, YOU NEED NOT LIKE, JUST RESPECT, THAT'S TRUE. WHY DO NOT HATE LEADS TO NOTHING. AND HATE IS NOT WHAT THE MONSTER MOTHER TEACHES YOU IS NOT EVEN? ^ ^ PAWS UP FOR KATY'S N 'GAGA

Katy is okay but Gaga can have me any day.

I don't love Katy, but I respect her. I love this video, I watched it a hundred times (for those who don't know, it's a video). I'm so against Monsters that hate on Katy <3 I'd love a duet. It'd be #1 for weeks I'm telling ya.

sweet

but they were friends in like 2008, then katy started disliking her.

I love the both of them!!! <3

against haters! :D

The best duet in the whole history would be of Katy Perry + Gaga

This is real but about 4 years ago :)
