Here is Katy Perry looking like a fit whore in red outside the Ed Sullivan Theater in New York City on Tuesday afternoon as she visits The Late Show With David Letterman. Look at her rocking that tiny little Herve Leger bandage dress before entering the Ed Sullivan Theater. I think it is safe to say if Katy Perry was a prostitute on the streets of New York in that dress I would certainly inquire on her price at the very least. So apparently Katy Perry did a full concert for David Letterman's audience yesterday. I figured most people would be done with it by the time the interview was over, much less the beginning of the first song. I am just saying Katy should be seen (preferable at a reasonable distance) and not be heard. Click on pictures to enlarge.
