Justin Bieber vomited twice on stage during his sold-out concert in Glendale, Arizona at the weekend. He left the stage immediately, but still returned to perform an encore. Blaming milk for the bad stomach, he later tweeted "Milk was a bad choice", borrowing a line from the movie Anchorman to explain his sickness. The top YouTube comment at time of posting was "It's not vomit, it's the new single."
