Keith Urban and Nicole Kidman

American Idol judge Keith Urban is the final decider on roles for this wife as she looks at movie scripts.

According to a report, Nicole defers to her husband and will only accept an acting role if Keith says she is allowed to do it.

The 45-year-old star always makes sure she runs her parts past her husband - who she married in 2006 and has daughters Sunday Rose, four, and two-year-old Faith Margaret with - to ensure they will ''work'' around the couple's family life.

She said: ''When I'm offered a role, I literally say, 'Is this going to work for our family?' And I ask Keith about it and there have been times when he's said 'no' and I've not done it, and there have been times when he's said 'yes' and we make it work.

''And I'm absolutely fine with that because I want my children and I want my marriage more than I want anything else. So it's really simple.''

Nicole - who won an Oscar in 2003 for her portrayal of Virginia Woolf in 'The Hours' - plays a lonely window in her latest movie 'Stoker' and admitted she much prefers to portray ''character roles'' rather than try to pull off a ''girl next door'' type character.

She added to Radio Times magazine: ''My desire, particularly now as I get older, is to play character roles. 'The Paperboy' is a character role and so is 'Stoker', and 'Grace of Monaco'. And it's a great thing being a character actor - the leading lady thing is fine but the interesting stuff is the character parts.

''I'm not interested in playing myself and I'm not interested in playing the same thing over and over again. I'm not good when I have to be the girl next door. That's just not my thing. The more extreme the better in a way.''
