Korean singer JB made her first debut performance yesterday on Mnet M!countdown singing her single "1987" that was released last month. It seems that MPlay Entertainment waited till now, when all the hot girl groups were cooling down, to let her have her try at the spotlight. There doesn't seem to be much information about her, but we'll be sure to keep our eye out for her. Everything about her just seems so cute and pretty, doesn't it? Her face, her dress, her voice, and even the song itself screams cute! Watch the performance and be the judge yourself! Thanks to jaeurazn for the tip!
