I'm not sure whether this would be considered a kilt sighting in the media, but someone shared a secret about kilts on PostSecret.

For those not familiar with the site, the idea is to create a postcard depicting a secret, mail it to the webmaster's address, and share it anonymously. Secrets run the gamut: serious, personal, deep, silly, fun, trivial. New secrets are posted each week so, the kilt card may not be visible after Saturday (Feb 6, 2010).

Here's a link to that specific card. Hopefully that will be available after it has been taken down from the main page.
