Nicole Kidman insists she spends ''every minute'' with husband Keith Urban when they're not working.

The 46-year-old actress, who has daughters Sunday, five, and Faith, three, with the country singer, along with son Connor, 19, and daughter Isabella, 21, with ex-husband Tom Cruise, claims she has a ''simple'' family life and always makes time for her loved ones.

She told HELLO! Magazine: ''We spend every minute together when we are not working. It's as simple as that. We have a very simple life together but an extraordinarily creative one.''

The 'Grace of Monaco' star feels ''lucky'' to have a partner who is ''totally committed'' to making their marriage work and insists she doesn't need to go out at night drinking when she's not working.

She said: ''We have two little girls that we adore and we're very blessed in the sense of having a family.

''We certainly talk about everything. We make the decisions together. Being home in Nashville feels like a normal life. I don't need much. I don't need to be going out at night. I'm a bit of a homebody. I live the drama of life in my roles.''

The actress says her family give her joy and make her feel ''totally satiated''.

She added: ''I get to play out my ideas and feeling through all these different characters, then I come back to just being Mama.''
