Nicole Kidman wants another baby so badly, she wishes every month she was pregnant.

The 47-year-old Aussie actress already has two children with husband Keith Urban - Sunday Rose, six, and Faith, 3 (who she had via surrogate in 2011). She is also mother to Connor, 19, and Isabella, 21, the children she adopted with then-husband Tom Cruise.

Despite the unlikelihood of any more children happening for the couple, Nicole admits she hasn't quite given up hope.

"I hope every month that I'm pregnant," Nicole told told Australia's KIIS 1065 on Friday, "but I never am. I would be jumping for joy if it happens. I'm 47, it won't happen."

Host Jackie O told her one of her own friends got pregnant at 49, something that clearly delighted the star.

"That’s incredible, what a fabulous thing. My grandmother had her last baby at 49 so you never know," she said. "I'm baby crazy. I love babies…kids, they are just extraordinary."

But what about Keith? Apparently he wouldn't be terribly thrilled about a third baby, according to Nicole. "He might not be jumping for joy," she laughed.

Bet he doesn't have any complaints about the actual attempted baby-making, though!
