This is actually a cut taken from last Saturday,17 th October's Episode of Star King.

Tiara's Eun Jung appeared on the show as a guest and she did an unexpectedly sexy dance at the beginning of the clip but she was defeated by a trainer who did a lot of difficult acts involving high body flexibility..

Anyway i think that she deserved the credits with her hot dance and her seductive face expression as well as her body,she is showing us another Tiara's leader in the show,now please enjoy her hotness!
