2AM's Jo Kwon congratulated the Brown Eyed Girls on their SBS Inkigayo win with a 'special' performance. On the October 23rd Inkigayo episode, The Brown Eyed Girls' "Sixth Sense" won Mutizen Song for the second week in a row. After they expressed their many thanks and prepared to put on their encore performance, Jo Kwon took center stage and hilariously mimicked the choreography for the song. The girls welcomed his spontaneous dance as they looked to be enjoying his adorable performance, singing behind him. Jo Kwon then quickly exited the stage, respectfully reserving the spotlight for the ladies. Meanwhile, the Brown Eyed Girls will be taking some time off and returning a week later with their repackaged album. Source & Image : KyungJaeToday via Nate
