If you haven't had enough of those Victoria's Secret girls, and Heidi Klum in particular, here's one last little look at Heidi, and her ass crack too. Yes, that's right, not only so we get Heidi Klum cleavage from the front, now we get cleavage from the back. Even hotter than all that, though, is the fact that you can clearly see that Heidi is going "commando." Add to that the super short skirt, and you've got a Britney Spears moment just waiting to happen. Sadly, Heidi's too smart for that.
