Justin Bieber vomited onstage Saturday during a show in Arizona.  See if you can tell what he had for dinner.   The Biebs left the stage twice during the show but like the little trooper he is,  he finished the show.  I don't understand how his dancers didn't start hurling when he puked right in front of them.  He apologized to the crowd.  All the girls with Bieber Fever still found him dreamy and swooned over his apology.  He's no David Cassidy.
