On the latest episode of KBS's 'Happy Together', After School's Lizzy went through an embarrassing moment when her voice couldn't quite reach the high notes of her latest song, After School Blue's "Wonder Boy". Lizzy started the incident by proclaiming that her voice is "on the level of a main vocal". Upon hearing this, the MCs requested that Lizzy sing a few verses from her single. However, when she attempted to sing, her voice wouldn't come out and she explained, "It's late at night so my voice is down." Although she attempted to try again standing up, her voice ended up cracking when she reached the high notes, and she couldn't hide her flustered expression. To ease her worries, MC Park Myung Soo cracked a joke, saying "Everyone has horrible voices these days." He then asked fellow guests 2PM to prove this fact, and they caused laughter in the studio by purposely singing off-key. Although it was probably an off-day for Lizzy, the MCs fortunately managed to smooth over a potentially embarrassing situation. Source: Newsen via Nate
