Nicole Kidman "Can Never Be Away" From Sunday

Adoring mom Nicole Kidman says she has a constant companion in her 17-month-old daughter Sunday Rose.

"I just can never be away from her, so she comes wherever I go, as you see. Have baby, will travel. She's OK (on planes), but honestly, we stay in Nashville a lot. That's why I don't work that much," the Oscar-winner says. "It's harder now to pack to her up. At 16 months, it's a different type of traveling. When they're 6 weeks, they're easier to travel with. And you're breast-feeding, so it's easy to feed."

It sounds like Sunday was a hit with Nicole's co-stars on the set of the new film Nine: "Sunday Rose was there on set," says singer Fergie. "I always wanted to go talk baby talk to her."

The adorable tot has been with her famous mom as she makes the PR rounds for the film as well. The pair arrived in Sydney, Australia this weekend for a very happy reunion with dad Keith Urban.
