Nicole Kidman's husband leaves her secret love letters.

The 'Grace of Monaco' actress finds the attention she receives from Keith Urban ''amazing'' and says he is very romantic.

Asked if Keith is romantic, she told French newspaper Le Matin: ''Totally! He leaves me a love letter every time we're apart. It's amazing to get that kind of attention from a man who loves you.''

The 46-year-old star, who has daughters Sunday, five, and Faith, three, with the singer, along with children Connor, 19, and Isabella, 21, with ex-husband Tom Cruise, left Los Angeles for Nashville, Tennessee because she's a ''country girl at heart.''

Asked why she refuses to talk about Tom but is open about life with her new husband, she said: ''Everything is different, simpler. I'm more confident within myself and calmer.

''It's no doubt due to the extra years that have made me more mature and surer of my beliefs and my choices.''

Meanwhile, the star filmed 'Grace of Monaco' in the South of France and Keith and the girls were there as often as possible.

She added: ''We try and combine work and pleasure. While I'm filming, my husband takes the children on a tour of the region. They go to the beach, the pool or visit tourist attractions.''
