Kings of Leon fans were not happy on Monday when the band cancelled its entire U.S. tour. Although the band said that lead singer Caleb Followill was "suffering from vocal issues and exhaustion," an insider close to the Grammy winning Tennessee band tells Us Weekly the problem actually stems from frontman Caleb Followill's excessive drinking.
"They are trying to get Caleb to go to rehab. It is mostly for alcohol," the source told the magazine. "[That's why] they ended up canceling the whole tour...he drinks like a fish."
Kings of Leon were forced to cut short a concert in Dallas on Friday when Followill abandoned the stage after telling the anxious crowd, "I'm gonna go backstage and I'm gonna vomit, I'm gonna drink a beer."
A second source reportedly confirmed to US Weekly: "It's true. Caleb's drinking is out of control and they are trying to get him into rehab. It's a dark demon he's been fighting for awhile."
Bassist and brother Jared Followill hinted at major issues in the band in a series of tweets over the weekend. The youngest Followill tweeted, "Dallas, I cannot begin to tell you how sorry I am. There are internal sicknesses & problems that have needed to be addressed. No words.” He then went on to tweet, "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."
However, Kings of Leon's representative stated that Caleb Followill was required to take vocal rest, and told Us Weekly that the band "look forward to getting back on the road at the end of September."
