Nicole Kidman and Keith Urban usually keep a tight lid on their personal lives, but the country singer couldn't help himself in an interview with Zane Low on Apple Music.

He gushed about Kidman and revealed how much of an influence she's had on his music over the years.

"She's got great taste in music – it's always visceral. It's just like, I don't know who the artist is, I don't know what genre it is, I just love this song. It's all that matters to her.

"You know what I've learned from her is to be more fearless in artistry and go for the curious place you want to go as an artist, don't question it," he explained.

"Her whole thing is 'oh I'm interested in that, I'm going to go over there,' it's not like can I do it? That's definitely had a big impact on my music in the last five to six years particularly."

The pair initially met at the 2005 G'Day USA gala and were married in 2006.

Kidman also opened up about how the coronavirus pandemic has impacted their family, as they have two daughters, Sunday, 12 and Faith, nine.

"We travel together, so we are always together, but never where you are in a house and you can't go to the store, to a restaurant of the movies," she said.

"Staying home, doing school from home and all of those things that everyone has been doing is a completely different life for us."

The Kidman-Urban family have never been happier despite the changes. "I love being in the kitchen in the morning so that when my kids come down, there's noise and there's joy in the home. That's really important to me," she said.
