Thank goodness for underwear.

Otherwise, the photo below would give us a Janice Dickinson crotch shot that would rival anything Britney Spears or Paris Hilton has ever poisoned our eyes with.

We have no idea who the old dude alongside this former model is, but he looks less than enthused to be holding hands with an insane Dickinson as she frolics way too freely. Even Tila Tequila wears more clothing than this. Occasionally.

Call us crazy, but in a match-up of elder super models, we'll take Heidi Klum nude over Janice Dickinson nude any day.
