The Dream: Who The Eff is Nikki?

Unless you are living under a rock, you've heard about The Dreams current relationship troubles with Christina Millian.   

You've also seen him pretty much acting like an asshole about everything related to his soon to be ex wife.  I don't get this dude.  He couldn't even fake being happy when he was in interviews, making snide remarks about the married life not being all it's cracked up to be and, etc.

He seems to put all of his business in his songs.  If you've ever heard his single Nivea Nikki, you understand, but with the recent Nikki Pt. 2 out on his new album, I have to ask.  Who the eff do you want??  The ex wife or the new ex wife?  Soooo what do you guys think about all of this foolishness?
