Hip hop duo Untouchable made their comeback last week with their 2nd mini-album and title track Living in the Heart. The original track features Brown Eyed Girls member Narsha but for this weekend's round of live performances, Secret's Song Ji Eun will be replacing Narsha on stage. Last week, Narsha was kind enough to grace us with her presence as she took the stage with Sleepy and The Action. Unfortunately for fans of this collaboration, she has her obligations to her own group, so Ji Eun is taking over. A representative of Ji Eun said,

"Ever since she finished promotions for her solo album, Song Ji Eun has been busy preparing for Secret's first mini-album which is set to be released later this month. But even in the midst of her activities, she has wanted to show a different style of herself, [which she will do by] performing Living in the Heart. Although Narsha and Ji Eun have different vocal styles, she'll give a whole new feel to the song."
