Brad Paisley's wife, Kimberly Williams-Paisley, has undergone surgery to deal with a health issue that started two years ago. In a post on social media, Kimberly revealed that she lost her voice almost two years ago while on stage at her annual Alzheimer's fundraiser in Nashville. "It was embarrassing & scary & it never quite came back," she writes. "It's been a challenging couple of years, but we finally got to the bottom of it. I have damage to my laryngeal nerve." She had the surgery this week and already "it is sounding so much better!!"
