But maybe it'll be good. They're both pretty talented.

uh oh

chris + justin vs ciara + usher who will win

chris coming to steal gaga shine next year

SHM, cant believe Chris is that desperate.

I for one, am super excited.

It's not desperate. We don't wanna talk desperate.

Anyway, this gives me LIFE!

do as u please

why is he desperate?

I have so much I could say but ill just say this... hope its good

Where tha hell does GaGa fit into either one of their categories? Sad pressed soul,ain't nobody thinkin about GaGa. This is about Earth Chris

Gaga's got everyone's minds.

This is the musical equivalent of Ciara collaborating with Willow Smith. And his fans are teenage white girls whose parents wouldn't dare let them listen to Chris Brown of all people . The jokes just write themselves sometimes.

Cus he surely begged Justin for this.

IKR? The things one has got to do..

I hope this kills Justin's career

Girls and Brown.

It's clear that if he was at the top of his career this duet would not happen

Oh no. Justin working with someone who has physically abused and has a short temper. Im so worried. Please. Someone stop him.
