Kings Of Leon's upcoming world tour has reportedly been thrown into jeopardy as the band rows over frontman CALEB FOLLOWILL's drinking.
The rockers are due to hit the road on 1 December (08) for the start of a major tour which will begin in Britain and take in the U.S., Europe and Australia.
But the band, who recently claimed to have quit their rock 'n roll lifestyle to concentrate on their music, are said to have fallen out over Followill's alleged refusal to give up booze.
A source tells British newspaper The Sun, "The others have warned Caleb over and over again that they weren't happy about his drinking but he carried on regardless. The lads have always fought but they usually sort it out the next morning. Things are completely different this time.
"The label is deeply concerned that if they don't sort out their differences the tour won't go ahead.
In a recent interview, bassist Jared Followill spoke of his concerns for his brother: "The only time we fight is when Calebs drunker than hes ever been so its not really him. He wakes up and he doesn't remember any of it.
