"We're definitely female-heavy! But as the girls say, 'The dog's a boy!'" Kidman joked. "At times, [Keith] just needs to escape with his guitar. Sometimes I'll find him in his closet playing guitar. That's when I know we really need to give him space."
Kidman and Urban married in 2006, and now share two daughters - Sunday Rose, 12, and Faith Margaret, 9. The actress also said that despite their busy careers, they always make sure at least one adult family member is home with their kids.
Kidman explained, "We never leave the kids, one of us is always there,. When Keith went to Nashville and I had to work late nights, I rang [my sister Antonia] and asked her to move in with the girls and she did, and brought along her kids. That's special."
As for Urban feeling outnumbered by the girls in his family, he at least has reinforcement with the family dog, Julian.
