BIBI's recent performance took an unexpected turn when the singer abruptly halted in the middle of a song. 

On the March 9th episode of tvN's 'Amazing Saturday,' Chung Ha and BIBI made a guest appearance. During the third round game for snacks, BIBI got to perform her rendition of Kim Kwang Jin's 'The Letter.' But in the middle of her performance, she abruptly halted saying, "Wow, I can't do this. I'm sorry. I guess I could do it before because I was young. Now I can't do it. I don't know how I did it before." and gave up the rest of her performance. 

While the show's panel and the caption encouraged her, some viewers questioned BIBI's ability as a singer following the broadcast. The relevant segment starts around the 18:16 mark in the video below.
