Jessica Simpson may have traveled the world and seen things most people only read about in a magazine, but I know something she was obviously not aware of. When in New York City if you want to walk over a subway grate on the sidewalk you better not be wearing hells of any kind. Why do you ask? Well if you put a heel in a little metal hole you look like an idiot as you try and walk away. Jessica found this amazing truth out when she arrived for the 11th Annual Ace Awards. At least she can laugh about.
