The Something Borrowed star exchanged vows with producer Neal Dobson at the Nashville, Tennessee home of her sister Kimberly Williams-Paisley, the country singer's wife.
Williams tells People.com, "We wanted an intimate, farm-inspired wedding. We basically planned an upscale keg party!"
Gushing about her new husband, she adds, "He grounds me. He allows me to laugh at myself and calms me down. He puts things in perspective."
