Nicole Kidman is deeply in love, but not happy

"Keith knows I want one, and he has been getting there slowly. My husband really wants a couple of years, he said, 'Where I just have you.' So it's kind of romantic. That's what we decided."

Meanwhile, the slender Australian star is bulking up for her new silver screen role in The Reader.

She has already put on 10lb and is planning to double her weight gain in the coming weeks, according to sources.

A movie insider reveals: "The part she plays demands that she gets fatter throughout the movie as her character slips into middle age."
