Kings of Leon cut short a concert Friday in Dallas, Texas after lead singer Caleb Followill told fans, "I'm gonna go backstage and I'm gonna vomit, I'm gonna drink a beer and I'm gonna come back out and play three more songs."

The rocker never returned to the stage, which forced the other members of the band to apologize to the audience. "Caleb's just a little unfit to play the rest of the show," said bassist Jared Followill. "We love you guys so much, but I know you guys fucking hate us. I'm so sorry. It's really not our fault, it's Caleb. He can't play the rest of the show. We will be back as soon as possible."

Though Caleb Followill has explained that the reason he left the stage was due to heat exhaustion and dehydration, his brother Jared's comments on Twitter after the incident suggest that Caleb's behavior may be part of a larger issue in the band. After apologizing again, Jared wrote "there are internal sicknesses & problems that have needed to be address" and "I know you guys aren't stupid. I can't lie. There are problems in our band bigger than not drinking enough Gatorade."

You can watch Caleb Followill address the audience at the show in Dallas in the video below. The clip also contains footage of his band mates apologizing for his abrupt departure.
