Keith Urban and Nicole Kidman recently celebrated their 10th wedding anniversary together, and in an interview with Hits Daily Double, the singer says that his wife influences everything he does.

"First and foremost, my marriage with Nic informs everything," he tells the music trade publication. "Nic is so unbelievably open; she doesn't keep things in or bottle them up. She's really a great communicator. Because of her, if I open up, every day, I'm listening and growing and learning. If I'm a better man, it's because of her."

Urban says many of the "really simple, tough lines" in his song "The Fighter" off of Ripcord come straight from his early relationship with Kidman.

"I had such a learning curve in our marriage! When she'd get scared, I'd think she was angry; then I'd get defensive, go tearing out the driveway at 90 miles an hour. And that's when it all gets pear-shaped," Urban recalls. "What she needs, and it's in the song, is for me to stay, to be close, to hear her. Get Closer; the album title alone was literally from this new awareness I had with this reality of how to react. When things are tough or upsetting, it's about pulling her close. That's what she needs, and I had to learn it."

Urban continues to use Sarah Buxton's song "Stupid Boy" as one example of how Kidman's advice and support came back as fruitful.

"Sarah Buxton had put out an album and I was listening on the bus. I said to Nic, 'I need a song like that.' And she said, 'Why don’t you do this song?' And I was thinking it was a woman singing. Nicole was so clear: 'You’re the stupid boy. Sing the whole song, and then at the end put it out there.'"

Urban and Kidman celebrated their 10th anniversary on June 25.
