(Cover) - EN Showbiz - Caleb Followill has joked that the pressure on Kings of Leon to exceed their enormous success is making him go balder.

Caleb is the lead singer of American rock band Kings of Leon, alongside his brothers Nathan and Jared on drums and bass respectively, and their cousin Matthew on lead guitar.

The 28-year-old rocker is currently promoting the bands latest album, which is the follow-up to the hugely successful 2008 smash Only by the Night, and Caleb teased that everyones high expectations has made his hair thin.

"I'm already going bald and you're making me go balder!" he laughed in an interview with USA Today when reminded of the publics eager anticipation concerning the future of Kings of Leon.

Despite having enormous worldwide success with groundbreaking hits such as Use Somebody and Sex on Fire, Caleb says the group feel they still have a lot more to offer the music world. The rocker is immensely proud of the bands fifth album, but thinks their future hits will be even more astounding.

"We're going to strike while the iron's hot. We still don't feel like we've created our best work yet," he enthused. (C) Cover Media
