Netizens and fanboys alike are buzzing over a set of photos featuring the 'nation's little sister', IU! IU recently attended a event for the Samsung Galaxy S 2, and photos of the star were uploaded onto an online community board on May 27th. Although she carries the nickname, 'nation's little sister', IU stunned her fans when she stepped out as a lady for the event. She's seen wearing a fashionable outfit that gives off a mature air, thanks to the chic jacket over a black dress. Her slender figure and gentle expressions are definitely attracting a lot of attention, and there's no doubt that she'll grab some high-end CFs soon. Netizens wrote, "You're becoming thinner and thinner. I hope you'll rest now", "How many schedules do you have… please take care of your health", and "Obviously, IU is the real thing. You're too pretty". IU is currently participating as a regular contestant on SBS's "Kim Yuna's Kiss & Cry". Source: Daily Sports via Nate
