Say Hello to Hank and Evie

1/30/2008 Stephen L. Betts Keith Urban and Nicole Kidman's pet names for each other have been something they've kept relatively quiet until now.   But "Hank" and "Evie" are using those pet names for a new clothing line, the Sydney Morning Herald newspaper reports. Keith has trademarked Hank Evie in the US and Australia, allowing the couple to clothe consumers in a variety of items. It remains a mystery why they chose these names, however.   Keith already had fans looking good in his concert T-shirts manufactured under the Hank Evie label, though few knew he owned the company or of the company name's origins. Nicole already has a $12 million deal to endorse Chanel No. 5 perfume, and has signed to do other endorsement deals. But this is the couple's first business venture together.   Their next venture: the couple's first child, due in July.
