In the same way that accents identify which Britney personality the paparazzi are encountering, wigs seem to be the key to which gender Paris is palling around with.
The brown wig, for instance, is for lesbian night at the Falcon, where she has been spotted three times in the past month (including one run-in with our own Marc Malkin). Her natural blond asymmetrical coif, however, is for dance night at equal-opportunity LAX.
She's even been known to don both on the very same night (as evidenced by the photo above)—proving the heiress has friends in many places.
