Nicki Minaj name change?

This chick confuses me I get confused by celebs alot but that is not the point. First, you want to be a 7 inch plastic doll second, you get the biggest fake butt ever third, I don't have a third but when I think of it, you will know. Now Ms. Minaj has taken to twitter to announce her name change. What will she answer to now, Roman Zolanski. I guess Nicki, I guess. How long do you have to be in the game to change your name?
