Charles Kelley of Lady Antebellum tells AOL's The Boot how he keeps his voice in tip top shape...

"I usually eat a lot of potato chips in the studio," he confesses with a laugh. "Because of the grease. When I'm singing, it helps me sing better for some reason, so we'll get some salty chips in there. I heard that trick from Celine Dion -- she does that. I think that's why I always gain 15 pounds when I'm recording an album! So that, and some hot tea ... and a lot of water."
