Kidman misses her kids with Tom Cruise

Nicole Kidman has the mommy blues.

As the actress raises 2-year-old daughter Sunday Rose with husband Keith Urban in Nashville, her children Isabella and Connor spend most of their time in L.A. with ex Tom Cruise.

"They live with Tom, which was their choice," the 43-year-old "Rabbit Hole" star admits to Hello! magazine.

Though she hasn't been photographed with Isabella, 18, or Connor, 15, since shooting "Australia" in 2007, Kidman hasn't given up hope that they'll one day spend more time together.

"I'd love them to live with us, but what can you do?" Kidman says.

Despite the distance between them, Kidman says she's extremely proud of how Cruise, 48, has raised Isabella and Connor in her absence.

"They are healthy and sane and together and are great, great people," she recently told the Associated Press. "So I'm not one of those people that needs to be reminded of what I have."
