Australia's stars Hugh Jackman, 40, and Nicole Kidman, 41, joined Luhrman Monday at the Museum of Contemporary Art in Sydney for a press conference.

Kidman, however, curiously kept her hands on her stomach while photographers snapped away at the cast members.

At one point, while standing sideways and posing with Jackman, Nicole sported what looked to be a telling bump on her belly.

Later on, Kidman and husband Keith Urban, also 41, attended a screening of Australia in Sydney, and Nicole commented on her hopes to have more children to the Daily Mail.

"I'm in a place in my life where I've had some great opportunities, and I may just choose to have some more children," she said.

Currently the actress has a four-month-old daughter named Sunday Rose with Urban, and two adopted children—Isabella, 15, and Connor, 13—from her marriage to Tom Cruise.

Kidman's comments echo those Angelina Jolie made recently about retiring from the spotlight to become a full-time mom.

Can't a woman be a good mother and an active movie star at the same time?
