On July 22 episode of SBS' 'Party People', Lee Hyori covered miss A's "Bad Girl Good Girl".
Just before she started, she said, "They (miss A) did really well with this song and I really liked the song. But also, I think this song really describes me well. When I dance, I consider myself as a bad girl but when I'm in love I like to think I'm a good girl." While she was covering the song, the creator of the song J.Y. Park couldn't help but smile and cheered her on. He and the audience absolutely loved the performance. Lee Hyori truly proves that age is just a number and she is able to pull off any performance she wishes to.
