The shape of Nicole Kidman's barely there belly is what the rest of us would consider a victory over the battle with the bulge. But the statuesque Oscar winner, who gave birth to daughter Sunday a mere four months ago, nonetheless sparked stork speculation in her hometown of Sydney when she hit the red carpet Tuesday in a snug white dress for the premiere of "Australia." The Daily Telegraph says the pregnancy "question [was] causing almost as much of a stir as her new movie." Also fueling the paper's probable wishful-thinking "Is she? Isn't she?" coverage: Nicole's comments at a pre-premiere press conference for the Baz Luhrmann-directed epic, during which she mused, "In terms of my future as an actor and stuff, I don't know. I am in a place in my life where ... I've had some great opportunities, and I may just choose to have some more children. I've no idea what is in my future, but I am very at peace with where I want to be. There are many things I want to do besides act." Still, Kidman laughed off the belly scrutiny during a chat with a Sydney radio station, saying, "No, I just have a little tummy. My god, I just had a baby four months ago -- give me a break!" For now, the glossy-visaged, surprisingly gray-rooted actress, 41, is just happy to talk about the ray of light that is Sunday. "She's a little stranger who we are just discovering," Nicole sighed to reporters, explaining that she was feeling a mite discombobulated because she and hubby Keith Urban had to leave the tot at home in Nashville for their quick trip Down Under. "I had to leave her for 24 hours," said Kidman, who is also mom to Isabella, 15, and Connor, 13, with ex-husband Tom Cruise. "I haven't done that yet, and so I'm still reeling."

Someone who can commiserate with Kidman over feeling mommy pangs while fulfilling professional obligations is Angelina Jolie, who's been out promoting "Changeling" and the DVD release of "Kung Fu Panda." During a sit-down this week with Britain's GMTV, the Oscar-winning mom of Maddox, 7, Pax, 4, Zahara, 3, Shiloh, 2, and 4-month-old twins Vivienne and Knox said she and Brad Pitt made the 24-hour trip to London with just the babies. She also revealed the problems she encountered when trying to breast-feed the double bundles at the same time. "It's very hard ... You look at the books and see, 'Oh, there's this football hold and you think, Ah, I can do that, if anybody can do that,' and it's a lot harder than it looks in the books," the actress admits (watch the interview here). "I did that a few times. I would take turns. It just takes a long time." Angelina says she shuttered the twin buffet last month. "It's very hard," she acknowledges. "I stopped at three months. [It was] about as much as I could do." Jolie, 33, who recently echoed Kidman's sentiments by saying she'll eventually "fade away" from acting, adds that being elbow-deep in diapers can make it tough to get glammed up for a night out. "We're trying to get ready for some event where we have to walk a carpet and somebody gets peed on," she shares, "and [we figure], 'Oh well, I guess we'll be wearing that this evening!'"

If you haven't yet had your fill of breast-feeding talk, Minnie Driver also has a few thoughts on the subject. The actress, who welcomed son Henry in September, tells Us that she's "never eaten more food in my life," something you'd never know from her slimline post-baby silhouette. "I think the breast-feeding is what burns it off," she posits. "I go for one big long walk with my boy every day. I live in the hills, so it's kind of up and down. I do some yoga, but I'm not doing a whole bunch yet. I still have a marshmallow tummy."

And finally, the aforementioned Nicole Kidman isn't the only big name being subjected to iffy procreation whispers. In the December issue of Allure, Scarlett Johansson said, "I always wanted to get married and have kids," and now that she's ticked off the first item from that to-do list by recently trading vows with Ryan Reynolds, rumblings have begun that she's planning to fulfill part two. A source close to the stacked starlet tattles to the Chicago Sun-Times that she and the well-muscled actor want to become parents "sooner rather than later." Seems Scarlett, who turns 24 on Saturday, "wants to be a young mother." The paper adds that the pretty pair is also open to the idea of adoption.
