Singer IU's 'naughty hands' have recently received the attention of netizens. On the December 13th episode of KBS-2TV's 'Win Win', IU was caught smacking the butt of surprise-guest miss A member�Suzy. When the background music began to flow, IU looked excited as she said "It's Park Jiyeon, isnt it?", thinking the surprise guest was T-ara's Jiyeon. But as actress Yoo In Na and Suzy stepped out, IU looked towards Suzy and remarked, "You said it wasn't you!", and playfully smacked her behind. When the MCs questioned why she would smack the behind on Suzy, IU explained, "I didn't think that Yoo In Na unni would be one of the guests, but I had called Suzy all day to ask her, and she said it wasn't her. She said she was in China." Netizens who witnessed IU's 'naughty hands' left comments such as, "IU's naughty hands are still cute", "Suzy and IU seem really close", and more.
