Keith Urban, Nicole Kidman Hoping for Second Child

Superstar Keith Urban's wife, actress Nicole Kidman, confirms the couple has not ruled out having a second child together. "We're hoping for another one," the Oscar winning actress (and mother of two adopted children with ex-husband, Tom Cruise) tells Australia's Sydney Morning Herald.

The star of the new film, 'Rabbit Hole,' also says she and Keith don't like being separated from their two-year-old daughter, Sunday Rose, for very long. "Time is the most precious thing. I'm very particular about how I spend it. I'm more reluctant to leave my family."

The Aussie-born actress who is now a Nashville resident adds, "Keith and I are very tight and we're never separated. If we are, it's no more than three days."

Nicole says that Sunday is "a Tennessee girl" and has reached what she and Keith call "the 'raccoon' stage because she's into everything ... She's just really hard to wrangle at this stage."

In the new film, based on the Pulitzer Prize-winning play by David Lindsay-Abaire, Nicole plays Becca, a mother who is grieving the loss of a young child. She says having her own child just a year prior to starting work on the film helped her understand the role. "When we first optioned the play, I wasn't pregnant. This [film] has been years in the making, so there wasn't a thought of being pregnant. I thought I'd never get pregnant. But I get what she goes through. I get her relationship with her mother, her sister, God. I get the way in which she is so angry."

Nicole has already been nominated for a Golden Globe for the role and is considered a front-runner for an Academy Award. She says the moment she read about the play she thought it would transfer to film, and she loved the character of Becca.

"I've been in other films where grief was a topic, but this felt very different," she notes. "It was more primal. And it's a topic we can't avoid because it's a part of everyone's life. What we love can turn into something we lose. The fear associated with that loss is a part of our human existence. I think that with this film it's very much about a family, as well, and it's about how a family works through their pain together."

Nicole says that because she loves being at home with her family, she's able to pick and choose film roles carefully. Among upcoming projects for her are 'Just Go With It,' a romantic comedy co-starring Jennifer Aniston and Adam Sandler. and 'Trespass,' a suspenseful film starring Nicolas Cage. She's also in the television movie 'Hemingway & Gellhorn' with Clive Owen.

Nicole will also return to Broadway in 2011 as the aging, drunken and sexually voracious Alexandra Del Lago in Tennessee Williams' 'Sweet Bird of Youth.' The character she portrays is considered to be one of the playwright's greatest stage monsters. Her most recent Broadway role was in David Hare's 'The Blue Room,' which ran from 1998 to 1999 at the Cort Theatre. 'Sweet Bird of Youth' opened on Broadway in 1959, with Geraldine Page as Alexandra Del Lago and Paul Newman as Chance Wayne. It is rumored that James Franco may portray the Chance Wayne character opposite Nicole.

'Rabbit Hole' is in theaters now. Keith Urban is already prepping his Get Closer 2011 World Tour, which kicks off in Australia in April and heads back to the States in June. Click here for ticket information.
