"I'm just trying to get better," Followill told TMZ.com cameras, who trailed him on the street as he walked with his wife, Victoria’s Secret model Lily Aldridge.

When asked if the tour will be rescheduled, Followill replied, "I don't know. We'll see how it goes."

TMZ.com asked Followill what caused him to walk off stage. "It's my voice," Followill said. But there have been rumors of bigger problems, with his brother and bass player Jared Tweeting, "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."

TMZ asked Followill how he'll heal his voice, though, and he said. "Try not to do interviews," before chuckling and walking off.

The band announced Monday that they're canceling the remainder of their U.S. tour.

"We are so sorry to say Kings of Leon are canceling their entire US tour due to Caleb Followill suffering from vocal issues and exhaustion," the band -- which also includes brothers Michael and Cameron -- said in a statement.

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