Nicole Kidman and her husband Keith Urban are using their celebrity status to branch out to the fashion-design world. The celebrity couple are planning to unveil their own clothing line, naming it "Hank Evie."

On using "Hank Evie" to name their fashion line, it is reported that the two words actually are the separate names Nicole and Keith used to call each other while they were still in the early stages of their relationship.

Keith openly revealed during a fan question-and-answer session that he would call Nicole "Evie" during the early stages of their relationship, while she would call him "Hank."

On their clothing line, Keith reportedly has already trademarked "Hank Evie" in both Australia and the U.S., with concert T-shirts as the only item being sold until recently. The couple will later on expand their collection, adding among others pajamas, boxers, belt buckles and other items into their fashion line.

Meanwhile, it's been an official issue that Nicole and Keith are expecting their first child together. No words on how long the Oscar-winning movie beauty has been along with the not-yet born baby nor it is mentioned on when she's due to give birth.
