Nicole Kidman covers the March 2014 issue of InStyle magazine, in which she spills some details about her still very romantic relationship with husband Keith Urban.
"For every single night he's away, he leaves me a love letter," she reveals. "Every single night of our relationship."
She also doesn't mind touring with her Grammy-winning husband.
"That's basically how I've seen most of America, on that bus," she says about life on the road.
"Keith and I are both gypsies at heart. We can make our home wherever we are. The girls [daughters Sunday, 5, and Faith, 3] are like that too now, so we take them everywhere."
In fact, the glamorous Nicole, 46, surprisingly says she's "country at heart."
"I have a real desire to be outdoors, a desire for simplicity -- a slightly slower, relaxed approach to life. A community, not a big-city feel. That's what I grew up with, and it's what I prefer."
As for her much buzzed-about role as legendary actress Grace Kelly in Grace of Monaco, which Variety reports she beat out "nearly every top actress in Hollywood" for -- Kidman stresses that she doesn't let the fear of living up to certain roles ever stop her.
"I always try to push through fear. I won't be crippled by it. People say, 'Oh you take such risks, or 'You're brave.' And I'm like 'Well, if you only knew -- inside I'm really frightened!' she admits. "But the way people navigate pain and fear is fascinating."
