they're friends with perez before. i saw a pic gaga, katy, and perez were playing. it's so freaking cute. but i don't know what happen after 2009 i think.
I don't dislike katy just her fans always have something to say like I post ARTPOP is gonna slay and without even mentioning katy or prism and a katy cat comes around saying ARTPOP will flop and prism will slay -_-
