Isn't this debate devolving into the other Kate Upton thread?
She's super hot, and no one, not even Otis, is going to kick her out of bed in any capacity. In the grand scheme of life, if you were to look at all people with 34D measurements (or whatever she is) that are natural, she is probably in the thinnest .5%.
That said, she doesn't have the body of a typical supermodel. If you look at the other women on the SI site, I don't really think that is a debate honestly. To use an NFL draft term, I think maybe her best "comp" is Tyra Banks. Tyra is a gorgeous girl, but at this age in her life, she is a bit thick. That's probably where Kate Upton is going to be in 15 years as well.
Can't we appreciate her for what they are she is and be done with debating what she is not?
