On SBS "Good Sunday - Change," singer Lee Hyori made a drastic change which led her family to disbelief. "Change" is a new section of "Good Sunday," where guests become something others would have never imagined them to become. In Hyori's case, she became a fat songwriter. Hyori went through four hours of make-up to receive her new image, upon completion, she went to her parents house along with Shin Dong Yup and Noh Hong Chul. When they arrived at the house, Hyori introduced herself as a songwriter named 'Choi In Ji'. She tried hinting to her parents by singing them a FinKL song, but both her mother and father failed to recognize their daughter's voice. Although her parents didn't recognize her, both of her sisters did. When Hyori revealed herself, her parents were beyond surprised that the fat girl in front of them, was their daughter. Maybe her parents were surprised because they were told beforehand, that their daughter would arrive a little later on in the show. Or, maybe they were surprised because Hyori would no longer be considered a sex symbol. And, we all know what that means. That means, no income FOR the singer AND her family. If you can't imagine a fat Hyori, check out the episode which airs on February 17. Here is an image of the transformation:
