Keith Urban puts marriage first

Keith Urban has admitted he has to put his marriage first otherwise his life can feel like a game of Jenga.

The 47-year-old singer keeps his wife Nicole Kidman, whom he married in 2006, as one of his priorities otherwise his work-life balance can start to feel like the challenging block-building game.

Speaking during a question and answer session at Country Radio Seminar in Nashville, he said: "Someone said one time, 'If your marriage isn't your priority, you're not married.'

"And I thought, for me that's so true. So as long as I keep her as a priority, everything else sort of seems to work. And when I don't keep it as a priority, it's ... Jenga."

The Australian hunk also revealed he would struggle to keep his schedule in order if it wasn't for the 47-year-old actress.

He explained: "I have a lot of people who help me ... starting with my wife, who is extraordinary at keeping everything sort of scheduled and balanced."

Meanwhile, Keith, who has battled drug and alcohol addiction in the past, previously credited Nicole for helping him to stay sober and encouraging him to go to rehab shortly after they got married.

He said: "I was very, very blessed to have Nic call an intervention on me. I didn't give a s**t about anything except turning a corner in my life and doing whatever it took for that."

The couple, who met at an awards ceremony in 2005, have daughters Sunday, six, and four-year-old Faith together.
