Fans of Justin Bieber got more of a show than they bargained for when the pop star vomited on stage during a live performance.
The incident occurred Saturday night in Glendale, Arizona as Bieber was starting his new "Believe" tour.
During his performance of "Out of Town Girl" Bieber turned away to vomit before running from the stage and returning to inform the audience "I'm sorry, I'm going to slow things down." USA Today reported that the 18 year-old pop sensation then went into an acoustic version of his song "Fall."

The troubles didn't stop there as the same situation happened a while later during a performance of "Beauty and a Beat" when Bieber ran off for a couple minutes.
Bieber returned to his fans saying, "It's hard for me, you know, not feeling great and throwing up in front of a bunch of people."
He then asked the crowd: "Will you love me even though I'm throwing up on stage? OK, I wanted to give you my best show ever, so do you mind if I finish it?"
Even with the stomach sickness Bieber was able to put on a great show. Jon M. Chu, creative director of Bieber's tour, reported to E! News saying, "The star of the show last night was Bieber, the ultimate professional."
The night previously Bieber was consuming milk which turned out to be a poor choice of pre-show beverage.
"Great show. Getting better for tomorrow's show!!!! Love u," Bieber tweeted. "And .... Milk was a bad choice! Lol. Goodnight Avalanna. Tonight was for u. I love u."
