In 2012, during the first show of his ‘Believe’ world tour, the American singer, Justin Bieber was so embarrassed when he threw up twice on stage in front of the audience. He was performing the song ‘Out of Town Girl’ when he suddenly turned around and puked, not once, but twice, while the dancers kept dancing and the track continued to play. He later returned to the show and started singing the acoustic song, ‘Fall’. But that’s not it. A few songs later, he again became sick and ran off the stage. After a few minutes, he returned again and said, “It’s hard for me, you know, not feeling great and throwing up in front of a bunch of people”.One more thing discovered though, was that Bieber was lip syncing to the whole song as when he threw up, the track was still going on with his voice.
