On the most recently aired episode of XTM “Adrenaline,” Lee Hyori made a special guest appearance and surprised everyone. Lee Chun Hee, Lee Hyori’s co-star from SBS “Family Outing” and a good friend, made such guest appearance possible. 

When Jung Gyeo Woon told the cast that he wanted to become a singer when he was younger, Lee Hyori suggested a spontaneous audition on the spot. She said, “You seem very robust. You’d probably do really well as a dancing singer. Let me see if you have the potential or not.” 

Jung Gyeo Woon got up on his feet and danced with all his passion and strength as if he is really doing an audition. Lee Chun Hee suggested, “why don’t you do the horse dance, too?” Upon Lee Chun Hee’s suggestion, Lee Hyori got up and tried the horse dance but she looked a little confused. She asked, “Wait, how do you do Psy‘s horse dance?”

After giving it a very short try, Lee Hyori soon gave up. She commented, “Is this how you do it? I don’t know. I think I’m a little behind in terms of trends now.”
