T-Pain was performing his hit song, “Bartender” over the past weekend in Denver 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. He didn't look happy at all.
