@ longtimefan: I know, right? Tyra seems to love the girls with sob stories, but not all of them can model (i.e. Thalia). As for Bianca, I see a resemblance to Nnenna, but Nnenna was beautiful (even though she annoyed me, I'll admit that she's gorgeous), and Bianca isn't imo.
The attitude-first bottom 2 has been around since the beggining of time, they did it with Brandy, they did it with Melrose, they did it with Jenascia, they did it with Nikeysha, they did it with Ebony, it's an inevitability that if you have a bad attitude the first week, Tyra is bound to keep you a bit longer
