GLENDALE, Arizona (AP) -- Justin Bieber lays it all out there for his fans during his show -- including his lunch. KTVK-TV in Phoenix has posted video of Bieber's show Saturday night during which he vomited not once but twice onstage. During one episode, he was near the front of the stage with several dancers, turned his back to the audience and let loose. Bieber left the stage after both incidents but returned each time. Fans sang the words while he was offstage. Bieber tweets, "Milk was a bad choice!"
