What Was Christina Aguilera For Halloween?

Celebrities have a way of making people notice them, that's what they're celebs. Christina Aguilera has always had a unique style, but she's stumping everyone who's trying to guess what she was for Halloween 2012.

So we're thinking that the pink wig is some sort of tribute to Nicki Minaj? Not exactly sure what Miss Aguilera was going for, but it sure is getting a lot of attention. Perhaps she was trying to start a new trend of her own. Perhaps next year some one will go as this, and the cycle will be complete.
