Kings of Leon are not breaking-up and will be back better than ever, the mom of three of the band members has revealed to Star Magazine.

Betty Ann Murphy has come out in defense of her sons Caleb, Nathan and Jared Followill, saying the trio -- along with cousin Matthew -- have no plans to split.

It has been rumored the hugely successful band was in meltdown when the Kings canceled the remainder of their summer tour after its lead singer, Caleb walked off stage mid-performance.
