SNSD's Seo Hyun and Super Junior's Kyu Hyun recently held a duet performance at SMTOWN LIVE WORLD TOUR in NEW YORK which took place in Madison Square Garden on the 23rd. SM Entertainment's stable of artists such as KangTa, BoA, TVXQ, Super Junior, SNSD, SHINee and f(x) were in attendance, and performed live in front of 15,000 audience members. Recently, SMTOWN uploaded the photos uploaded onto their official Facebook and the photos have been garnering much attention, especially the one of Seo Hyun and Kyu Hyun performing a duet together. The two looked to be more than just a little friendly, stirring the envy of fans everywhere. In one photo, only the back of the two can be seen but Seo Hyun is leaning her head towards Kyuhyun's shoulder and the two look like they could possibly be holding hands. The two easily look the part of a couple with their skinship. How do you think CNBLUE's Yong Hwa would feel upon seeing these shots? Fancam video (begins around 3:45) Source: Star Today Tip: Mel
