T-Pain was performing in Denver over the weekend when the audience couldn’t keep their balls to themselves. The singer/rapper was performing his hit song, “Bartender” when a volleyball hit him in the face, he immediately left the stage and didn’t return even after his team tried to get him to continue performing. Witnesses at the show said that T-Pain had warned the crowd that he would stop the performing if volleyballs continued to be thrown his way, and that was the last ball.
