During a recent Christmas show, pop star Justin Bieber brought out his little sister Jazzy to help him sing a song. This touching video started with Justin talking to his sister on stage, and then him telling her that he loves her. Later on, when Jazzy gets a little more comfortable on stage, she helps her brother sing his hit song “Baby.” The video is very sweet and touching, and shows that for all the hate he gets, Justin is actually a pretty good guy
