Watch out, Keith Urban! Nicole Kidman has her eyes on Aaron Eckhart, who stars with her in their upcoming movie Rabbit Hole.

At the movie's New York premiere on Thursday, Kidman said that she "begged Eckhart to play opposite her," and told People that he'd make a terrific husband on- and off-camera. "I think he would," she said. "Because he's very loyal and because he has a strong moral center — and he's fun."

The Oscar winner, who has been married to country star and fellow Aussie Urban since 2006, plays Eckhart's wife in the movie, which is based on a Pulitzer Prize-winning play about how a couple copes with the loss of their son.

Eckhart, who was linked to actress Molly Sims last year, isn't sure that he'd make a great husband. "I don't really know," he said. "God, I'd be as good as anybody else — there are some terrible husbands out there." The movie will open to a limited release on December 17, before expanding nationwide on January 14, 2011. —ISHITA SINGH
