Lady Antebellum members Hillary Scott, Charles Kelley, and Dave Haywood all have success in their genes. Hillary is the daughter of Grammy-winning country singer Linda Davis, while Charles is the younger brother of pop-singer Josh Kelley. But perhaps no one's family has had more widespread influence than Dave's. His father invented the nightguard teeth-whitening method, which has garnered worldwide use in the last 20 years.

"He's a dentist, and back in the 1980s, he came up with the procedure," Dave explains to GAC. "He's been on '20/20' about it and everything. In the dental world, he is a rock star. He's the Bruce Springsteen of the dental world!"

Helping keep his teeth clean isn't the only thing Dave can give his Dad credit for. "My dad taught me how to play guitar," Dave explains. "My family's really musical. They're kind of like a nerdy Partridge Family. My dad taught me to play guitar back in middle school, and my mom taught me how to play piano in elementary school ... Everyone in my family sings, so it all comes directly from them."

Lady Antebellum are currently on tour with Kenny Chesney. They are also planning on taking the stage at the CMA Music fest June 12, alongside Jason Aldean, Jake Owen and Little Big Town.
