Singer Yoo Hee Yeol complimented singer IU and girl group SISTAR's Hyorin.

Today, Yoo Hee Yeol held a press conference for KBS 2TV "Yoo Hee Yeol's Sketchbook - 200th Special." For the most memorable guest for his show, Yoo Hee Yeol said, "I was shocked when I first saw IU. I was confused what she was when I saw her play the guitar and sing."

He also said, "I also vividly remember SISTAR's Hyorin. She dressed up as Shrek and sang for the Christmas special but more than her looking funny, I was impressed with how good she was at singing."
