In the episode of SBS TV’s Challenge! 1000 Songs that aired on March 4, Lee Sun Jin and gymnast Shin Soo Ji made a guest appearance and sang “Be My Baby.”
After Lee and Shin finished their performance, host Lee Hui Jae asked MBLAQ’s Chun Dung to come to the stage, saying, “Please wait a second. I saw something.”
Lee asked Chun Dung to show his “Be My Baby” dance again, saying it was weird. Dumbfounded by what he said, Chun Dung danced along “Be My Baby.”
However, all other guests said his danced seemed funny and Chun Dung got embarrassed, saying, “Didn’t the Wonder Girls dance like this?”
Eventually Chun Dung said sorry to the viewers for not remembering the choreography of “Be My Baby” correctly. At this, Lee Hui Jae said, “It’s not that all idol members dance well.”
In the episode, MBLAQ, Lee Mu Song, Sa Hee, Yang Taek Jo, Goo Ji Sung, Han Moo, Jung Jong Chul, Lee Sun Jin, and Shin Soo Ji made a guest appearance.
