Kings of Leon Cancels Remaining U.S. Tour Dates

Kings of Leon has cancelled the remaining dates of its U.S. tour, TMZ has reported.

The lead singer's health issues are to blame.

"We are so sorry to say Kings of Leon are canceling their entire U.S. tour due to Caleb Followill suffering from vocal issues and exhaustion," a rep for the band said in a statment.

"The band is devastated, but in order to give their fans the shows they deserve, they need to take this break. Unfortunately, the U.S. dates cannot be rescheduled due to the band's international tour schedule."

Ticket purchases will be refunded, and the band will resume touring in Canada on Sept. 28.

The news comes on the heels of a troubled weekend for Kings of Leon.

Caleb Followill walked offstage at a Dallas concert Friday night after promising the audience he would return. He never did.

The band was 11 songs into its set at Gexa Energy Pavilion in Dallas -- where temperatures were in the 90s Friday -- when Caleb addressed the crowd in a disjointed explanation.

"My voice is completely 100-percent wrong, I'm sorry," the frontman told the crowd, according to E!.

According to a report in The Sun, Caleb then insisted he was not drunk, but was going backstage to drink more -- and vomit -- before he returned for three more songs.

"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... I'm about to fall down here because I'm so goddamn hot.

"I have no goddamn idea what the f*** is going on, all I know is that I'm married to the prettiest f****** 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," The Sun quotes him as saying.

The 29-year old singer, who married Victoria's Secret model Lily Aldridge in May, did not return to the stage.

Jared Followill apologized to the crowd on his older brother's behalf.

"We are so unbelievably sorry -- there's no words right now," the guitarist told fans, according to E!. "Caleb's just maybe a little unfit to play the rest of the show. I know you guys f**king hate us...It's really not our fault. We will be back as soon as possible...F**king hate Caleb, not us."

A video of the performance that was initially published alongside early media reports of the incident is no longer available for viewing, "due to a copyright claim by Vector Management."

Shortly after the interrupted show, Jared Followill took to Twitter to apologize further:

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

On Saturday, he tweeted once again, saying "I love our fans so much. I know you guys aren't stupid. I can't lie. There are problems in our band bigger than not drinking enough Gatorade."
