"She is not very pretty" is an understatement. She is gross.
Maybe because people keep bringing her up? Thus giving her more exposure and making her more famous? How do you think Justin Beiber became a household joke? Because people keep talking about him. Ooops, I just did it didn't I?
Also, she would probably be considered as curvy in many regions of the country where the morbidly obese is a common sight. Who's more attractive? Kim Kardashian or this "model" that looks like your next door neighbor in Mississippi? Caitlin FInley
That's my only guess.
She is in her own way to some but that's all she has going for her as she has no brains to speak of and horrendous taste in men judging by Kayne. Her beauty won't last forever or much longer then she will just be another has-been
