Since she and husband Keith Urban made Nashville their home in 2006, Nicole Kidman is content to live the country life out of the spotlight.  But InStyle’s March cover girl not only gives readers a rare glimpse at their relationship, she reveals just how much her country star hubby is a romantic at heart.

“For every single night he’s away, he leaves me a love letter. Every single night of our relationship,”; admits Nicole, who says the longest they have been apart is 14 days.

The Oscar-winning actress likes to keep the family close and says she and her youngest girls, Sunday, 5, and Faith, 3, love to hit the road with Dad on his tour bus.  “That’s basically how I’ve seen most of America, on that bus,” she says.  “Keith and I are both Gypsies at heart. We can make our home wherever we are and the girls are like that too now, so we take them everywhere.”;

While it’s hard to imagine Hollywood’s glamazon roughing it on a tour bus, Nicole admits she embraces life on the road fully, including chowing down on fast food! “Keith and I eat at Wendy’s,”; she says. “You’ve got to remember I’m with a musician on a tour bus, we do drive-throughs.”;
