BRAD & KIMBERLY: 10 YEARS
Known in country circles as a prankster, Paisley shares a sense of humor with actress Williams. The joking started on their 2003 wedding day: Family and friends had been invited to Malibu, Calif., for the engaged duo's wedding rehearsal, but when Williams suddenly appeared in a white dress, guests realized they were about to witness the real thing! The singer – who has sons Huck, 6, and Jasper, 3½, with Williams – credits that humor with keeping his marriage on solid ground. "Making each other laugh creates a bond," he says.
