With a little help from Girls' Generation's YoonA, Lee Hyori sang Fin.K.L's "To My Boyfriend" that gave the guests and the viewers alike a feeling of nostalgia. The 1998 track is considered to be one of the most iconic girl groups songs in K-pop history and what better way to remember it than a member of Fin.K.L, Lee Hyori, to sing it!

Lee Hyori, who clearly still hyped up from the night before, grabbed the karaoke mic next morning to wake everyone up with some songs.
