If it were up to him, Nicole Kidman wants to have more kids with Keith Urban as the "Photograph 51" as she gushes about the "American Idol" judge.

In a new interview for The Evening Standard, the 48-year-old actress said that she would have "liked to have been able to have more children with him.

"Also, I love him. I'd love to have more years, why not? But at the same time I am grateful I even met him. It's a big world," she said.

Nicole Kidman and Keith Urban have a house in Nashville, and also in Australia. But they are temporarily living in London while she's finishing up her contract for the West End play, "Photograph 51."

"From my daughters it was like, 'Yay, London, Winter Wonderland!' although there was also discussion of bringing our two cats over, which didn't eventually happen," she said. "My husband, I think, has made 15 trips over four months."

"That's commitment. I owe him a big thank you. He said, 'Go!', and it was so beautiful, because we really don't get that involved in each other's work," she explained, adding that husband Keith Urban didn't even read the play so he had a "very lightweight understanding" of what the "Photograph 51" is about.

"He then came and saw it in a preview and he came back afterwards and he was crying and he said, 'Now I know why we're here.' To be validated like that by your partner was wonderful, because this was a big ask," Nicole Kidman added.

Nicole Kdiman also makes sure to be always there for husband Keith Urban, even if their schedules don't always meet.

"He's a touring musician - they're used to being on the road,' she told Sunday Mail. "That's what he's always done and he loves it. He's willing to travel and make it work."
