In the show I thought AJ was just an emo chick who was recruited through myspace and didn't know whether she really wanted to model or not. She was eliminated because she's all anti-pop-culture and was less than enthusiastic about portraying a pop-icon.
But it turns out she's more than just an emo teen rebel. She actually wanted to model and I can assume she's kept her mouth shut about stupid stuff like wearing clothes she doesn't like or changing her hair to some thing different. I mean she is over 20 it's time she grew out of it.
