Singer Keith Urban, who might be better known as Mr. Nichole Kidman (we're told he has fans, we just haven't met one yet), is suing another Keith Urban over the domain name keithurban.com. The second Urban is not a singer. Nor is he married to a celebrity. It should be noted that the site in question is predominately a gallery of the second Urban's paintings, and seems to make no reference to the singer. That, and it's a decidely better than the singer's (snicker, snicker) .net address.
