2PM's Nichkhun recently became a spokesmodel for "J.ESTINA", a popular jewelry brand worn by the beloved figure skater, Kim Yuna. After using Lydia Hearst, one of the world's richest heiresses, for the beginning of their 2011 campaign, "J.ESTINA" has now turned to Nichkhun for the brand's first ever male spokesmodel. A representative for the popular jewelry brand said, "Nichkhun has a cute and gentle image so we thought he'd be the perfect prince for our 'J.ESTINA' princess. He showed off his great manners at the shoot, making everyone believe that he is really a prince. Through this campaign, we hope everyone feels J.ESTINA's lovely sentiment". Nichkhun was also pictured wearing a black backpack, which became an instant hit and is now being called the 'Nichkhun Backpack'. It was said that the brand has been flooded with calls regarding the backpack and because of this, the backpack is going to be released sooner than intended. The idol has recently been named one of Korea's top CF stars, and is currently appearing in MBC's "We Got Married". Source: BNT News, Hankyung
