Nicole Kidman is constantly "inspired" by her husband.

The Hollywood beauty is married to country singer Keith Urban and the pair have daughters Sunday Rose and Faith Margaret together.

Nicole has gushed about her partner, explaining that she has infinite love for him.

"He inspires me. We met later in life and when that happens you have a much better chance of really going to a deep place," she told the UK edition of OK! magazine.

"When you're younger - sometimes not, my parents met when they were 23 - but for us, we met later in life, and we know who we are and where we're at. And we are very fortunate."

The actress is happy to support singer Keith with his career too.

"Australia will always be my home country. But home can be a place where you're happy with your loved ones. We're based in Nashville because Keith's career is country music," she said. "That's his passion, so you have to live in Nashville if you're in country music. That's where his work is and I'm perfectly happy there. I'm glad to be able to support him."
