Valentine's Day may have already passed by this Monday, but KBS's Music Bank wasn't going to let it pass by so easily, by having their own post-Valentine's Day special stages. Following their collaboration with MBLAQ last week, girl group SECRET linked up with boy group�TEEN TOP on today's Music Bank for a special performance of SECRET's hit song, 'Shy Boy'. There was a time when SECRET became a hot topic for imitating TEEN TOP's "Matrix" dance on stage of their "Shy Boy" performances. During the recent Lunar New Year, TEEN TOP transformed into "Shy Girl" for the special program, "2011 Star Dance Battle." TS Entertainment stated, "SECRET will be performing 'Shy Boy' with TEEN TOP on Music Bank. As much as they will be giving a new performance, we hope for everyone's anticipation." Check out their special stage below! The Teen Top boys also performed their "Supa Luv A-Rex Remix" for the first time.
