PrivacyWatch celebrity sightings are submitted by our readers, and are posted several times a week, so send them in often—the fate of the universe relies upon it! Submit yours to tips[AT]defamer.com (please put "sighting" or "PrivacyWatch" in the subject line so we don't lose them) and tell everyone about the time you saw Stephen Hawking flirting shamelessly with a restaurant hostess in Pasadena.
