Reportedly, "They Don't Know", Chris Brown's second single off his forthcoming album, X, will include never-before-heard vocals from Aaliyah.

I don't know whether I should celebrate or cringe.

im not a fan of chris music i do dig the song fine china i think its one of the best on radio now. i wish everybody would just back off the kid and encourage him 2 grow up and out of stupidity.regardless of the bullshit he is human everybody has feelings nobody deserves 24/7 bashing they did it to michael and now thats he is dead the world of haters still doing it

His past indiscretions are of little concern to me; I want to see if the next singe is worth the anticipation. Soon we will know because it will drop on Monday, accompanied by a new video.
