Justin threw up onstage!

Talk about a major OMG moment! At his first Believe tour show in Glendale, Arizona, Justin Bieber threw up onstage while singing his song "Out of Town Girl." After he puked, Justin ran offstage. Just a few minutes later, the star came back onstage and asked the crowd, "OK, I wanted to give you my best show ever, so do you mind if I finish it?" He also asked Beliebers, "Will you love me even though I'm throwing up onstage?" We think it's awesome how dedicated Justin is to his fans!
