HOW DO THEY MAKE IT WORK?

Nicole Kidman revealed in an interview how she and husband Keith Urban make the most of their time off. Kidman explains that they keep work out of the house as much as possible.

'Obviously I work hard, but when I'm off, I'm off. Keith and I are very good at immediately clicking off because we have a really good life in Nashville that's very simple, quiet and nourishing because we've made it like that."

Kidman explained that the couple does not have a TV in the bedroom and that computers in bed are strictly forbidden.

The Australian actress moved to Nashville with Urban, since the city is the center of the country music world, and travels to New York or Los Angeles when her work demands it.
