The intrepid girl reporter went under less cover than usual to make a point of some nature about the outfit Sienna wore at the Factory Girl premiere. Her findings? Well, apparently, dressing like a cheap hooker attracts the wrong sort of attention. Listen up, ladies:

Men lose all inhibition when confronted by a woman in panties."You making a porno?" one queried. "Cause I'd like to make a porno with you." Another proposed marriage and still another proposed a sexual act that we can't write about in a family newspaper. Several dudes offered to buy me some beers across the street in Penn Station.

So basically, everything Piazza had hoped for came true! We hope this means she'll start going pantsless more often.
