Justin Bieber vomits mid-concert on Saturday night at the Glendale, Arizona premier of his Believe tour. The first of two times was in the middle of "Out of Town Girl", during the dance number when he turned around and vomited. The dancers continued to dance and the background track continued to play. Bieber left the stage, when the DJ took over momentarily.

In Bieber-fashion, the superstar returned back on stage saying "I'm sorry, I'm going to slow things down." But a few songs later, at the beginning of "Beauty and the Beat," Bieber ran off-stage again.

When he returned, he said to his supporting fans, "It's hard for me, you know, not feeling great and throwing up in front of a bunch of people. Will you love me even though I'm throwing up on stage?" The answer was obvious!

Later that evening, Justin tweeted to his 28 million followers that he's "getting better for tomorrow's show." He also tweeted "And...Milk was a bad choice! Lol". Hopefully Justin will be back in good health to continue his sold-out tour.
