'K-Pop Star 2' contestant Andrew Choi performed Justin Bieber's "Baby" on the latest episode of the music audition program, where only three lucky contestants remained in the battle for the final prize.

Changing up the hit Canadian pop song into a smooth R&B style, he wowed with his usual commanding voice and sultry tones. However, the judges felt that he lacked a certain something. "Andrew Choi is the most improved out of anyone, but for this stage, his body froze up due to his ambition to win," J.Y. Park criticized.

"It would've been better if you had performed without greed," BoA said. "I was disappointed by this performance's differences from the practice version."

Unfortunately, Andrew Choi was dropped from the final three, with Bang Ye Dam and Akdong Musician going on to the final round.
