It seems the Kings Of Leon are no longer “on fire” thanks to Caleb Followill’s seemingly "drunken" onstage rant this weekend.

According to digitalspy.com, the rockers were forced to finish their Dallas gig early after the frontman shocked fans by storming off mid-way through their set to “vomit” and “drink a beer.”

In video footage posted on YouTube, the singer is heard telling the audience,

“My voice is completely 100 percent wrong. I’m sorry… Do you know what? I’m going to drink some beer and I’m going to drink some tequila and I’m going to have a good time and for the record I’m not drunk… I’m just f****** hot.”

But it didn’t end there. The 29-year-old, who recently tied the knot to model Lily Aldridge, continued,

"I'm about to fall down here because I'm so goddamn hot. I have no goddamn idea what the f**k is going on, all I know is that I'm married to the prettiest f**king girl in the whole world. I'm gonna go backstage for a second. I'm gonna vomit, I'm gonna drink a beer and I'm gonna come back out here and I'm gonna play three more songs."

Leaving his brother and fellow band member Jared to do the awkward explaining, he apologised to fans, telling them,

“We are so unbelievably sorry, there’s no words night now, honestly beyond our control. Caleb's just maybe a little unfit to play the rest of the show. We’re so sorry guys, we love you all so much. I know you guys f****** hate us, I can’t apologise enough. It’s really not our fault. He can’t play the rest of the show. We will be back as soon as possible. F****** hate Caleb, not us.”

And if that wasn’t enough to send fans into a frenzy about the state of the band’s future – Jared later said on Twitter,

“Dallas, I cannot begin to tell you how sorry I am. There are internal sicknesses & problems that have needed to be addressed. No words.”
