Justin Bieber must have been really nervous on the first night of his "Believe" concert tour in Glendale, Arizona. The pop star puked on stage... twice! In the middle of performing the song "Out Of Town Girl", Justin vomited and took a quick break. Check out the video of the unfortunate incident below.
After that, he went on with the show but was forced to leave the stage again while singing "Beauty And The Beat". "It's hard for me, you know, not feeling great and throwing up in front of a bunch of people," Bieber told his screaming fans who didn't seem to mind what happened as they cheered him on all throughout the concert. The 18-year-old heartthrob gave his "Beliebers" a clue on what caused him to throw up when he tweeted: "And .... Milk was a bad choice! Lol".
Do YOU think J.B. is Lactose intolerant, or did he just have a severe case of "Bieber Fever"? What do you think about his "the show must go on" attitude? Leave a comment below.
