There’s no secret to Brad Paisley and wife Kimberly Williams-Paisley’s successful 11-year marriage.

The country star tells Wonderwall how then his relationship has lasted so long in a world of celebrity divorce.

“I don’t know if there’s a secret. I think you have to have the same sort of priorities and outlook,” he says. “You’re sharing a car. You’ve got to want to be going to the same place.”

Brad adds, “You have to decide early on that failure’s not an option and that you’re going to evolve together. You’re going to change. We’ve been together now for a decade. You’re going to change. I’m so different than the total hillbilly she met.”

That hillbilly and his wife have welcomed two little boys into the family, William Huckleberry, 7, and Jasper Warren, 5.

The clips made BP's fans' days but clearly upset some big wigs at Sony Music, as Brad noted with a screenshot of an email he received.
