Katy Perry obviously looks like tears of joy. Nicki Minaj looks really really fake. Madonna... I don't care about her anyways. I love Nicki and Katy though. :L

wait, why does madonna have make-up on in this picture?

LMAO madonnas

I think for Madonna, instead of an exclamation point it should be a "..." it matches her expression more.

madonna's face is pure meme material

No.

Katy and gaga are friends though, right? :)
