During the December 22 broadcast of Mnet’s ‘Golden Tambourine’, TV personality Kwon Hyuk Soo enlisted the help of Girls’ Generation’s Sooyoung and comedian Lee Se Young!

The show made a concept wherein cast members formed different teams and inviting guests to compete in karaoke challenges, and Kwon Hyuk Soo, who is the head of the ‘Yam’ team, went back to the ’90s for his karaoke challenge!

Sooyoung and Lee Se Young made their transformation into ’90’s female duo BiBi to sing their hit song from 1997 “Skyground Starground”.

The duo’s costumes fit in perfectly with the ’90s vibe, the audience got riled up, and Kwon Hyuk Soo’s attempt at rap made the performance a big blast!
