Nicole Kidman Visits Children's Hospital in Sydney With Her Own Kids

Nicole Kidman visited a children's hospital ward Thursday with her son and daughter shortly after they arrived in Sydney for her widely anticipated wedding to Keith Urban.

Isabella, 13, and Connor, 11, flew by private jet from Tokyo where they were accompanying their father, Tom Cruise, on a publicity trip, Australian media reported. Cruise and Kidman divorced in 2001.

The children were driven to the luxurious mansion on Sydney Harbor that Kidman and Cruise once shared, accompanied by their grandmother Janelle, and left soon afterward with Kidman to visit Sydney Children's Hospital.

They spent about two hours visiting the oncology, hematology and neurology wards, chatting with patients and officials.

Photographers, camera crews and fans jostled for position as they left the hospital, blocking one of the exits at one point. "If everyone can just not get too dangerous," the 39-year-old actress said.

Elizabeth Crundall, chief executive of the Sydney Children's Hospital Foundation, said she was surprised by Kidman's visit.

"To actually take the time out from her own wedding for a couple of hours was stunning, extraordinary and wonderful," she said.

Kidman has reportedly asked guests to make donations to charity instead of buying wedding gifts. She and Urban, a 38-year-old country music star based in Nashville, Tenn., are expected to wed in a lavish ceremony Sunday night.

Work continued Thursday on erecting a marquee at a gothic-style sandstone Catholic church in the beach-side suburb of Manly -- the presumed location of the wedding.
