For me personally, Karlie really is one of the prettiest, and I also think she has one of the best bodies, if not the best. That is just me though, I know not many would agree with that, but I really do find myself most attracted to, and amazed with, her body. It is just incredible and it blows me away every time I see it. However, I don't know how anybody could ever dispute her skill at modeling, and that natural spark/charisma you mentioned, because it is clearly there and obvious to see.
