Khloe Kardashian was never known as the hot one, at least not in comparison to her sisters Kim and Kourtney. And now she has Kendall and Kylie coming into their own as well that she has to measure up to. Most people would probably choose Kim as the hot one but here we always thought Kourtney was. But then we changed that thinking again with Kendall battling for the top spot. Its not like any one of these sisters is un-attractive in anyway, but it seems very easy to be able rank and compare them. But over the last year and half, Khloe has apparently done quite a bit of work on herself to change that reputation and we have to give credit where credit is due.
