Oh and a word or two for Christina stans coming here and spoiling the thread. I could state some facts, but i'm pretty bored after all this time, and there is no need for that. At this time tho, P!nk's voice is even better than Christina's, and that's a damn fact.
Now please go away cuz you have nothing to do here, pressed fools.

This is the list of some of the suggestions from different posters on forums that hold at least some credibility, even though some have very minor chances of happening. Put points from 1 to 10 next to the artists that you wish she collaborated with.
1 = P!nk please tell me its just a dream and you didn't collaborate with that flop
10 = yesss my life is complete now

My ideal 10-point worth collaboration would be P!nk+Dido, but I don't think that's gonna happen
