"I don't think you'll talk to one person who didn't make it in a marriage who's not gonna feel that way," she admitted. "The intention of being married is the vow, right? You want to put everything into it to make it a success. [Marriage] was the one thing I didn't want to fail at. People can say whatever they want to about me, and I don't get too affected. But I didn't want them to think I was a failure."

As for Gavin, he said of their divorce, "Well, if you divorce America's sweetheart, you're in trouble. Or rather, if she divorces me. So … I don't read [headlines], but I know I've been portrayed as a bad guy." Despite that, Gavin claimed that his priority was their kids, noting, "She's the mother of my children and one of the most incredible girls in the world. I wish her all the happiness in the world, and that's the true sign of love. As I'm sure your favorite artist Sting said, 'If you love someone, set them free.' "

They exchanged vows in a chapel which he built on the estate. According to Page Six, Gwen's parents Dennis Stefani and Patty Flynn were among those in attendance at the nuptials.
