On stage in Arizona Saturday during his “Believe” tour, Beiber wasn’t feeling too great because he let it all out in wet chunky bits rather than in dance. In the video Beiber turns his back to the stage and vomits. Good thing he wasn’t lip-syncing..

The next tweet from Beiber’s Twitter read “And …. Milk was a bad choice! Lol”

He was able to sing a 21-song set, don’t work so hard J-Beib..
