Which stork-awaiting star denies tippling, which had a near toppling and whose uterus is under scrutiny by the tabloids? Here's the latest incubation news:

For years, Nicole Kidman has spoken longingly of her desire to become pregnant, and now that she is, it's likely she's doing whatever she can to stay healthy.

Keith and Nicole at the Oscars on Feb. 24

So many were scratching their heads this week over a report from veteran gossip maven Cindy Adams, who claimed the diamond-draped Oscar winner asked for and received white wine at the Academy Awards Sunday night.

"Boozing backstage during the Oscar-cast is a no-no," wrote Adams. "But if you're pregnant Nicole Kidman it's a yes-yes."

Faster than you can say "defamation," Kidman's rep unloaded both barrels on Adams, who last year accused Nicole Richie of smoking while pregnant (turns out she wasn't in town when the purported puffing sighting took place).

"I have to tell you that Nicole Kidman most certainly did not drink white wine or any other alcoholic beverage backstage," rails her irate mouthpiece to Perez Hilton. "She had water and lemon zinger tea. That's it. I know. I was there with her."

Not content to leave it at that, the peeved publicist decides to go for the jugular, adding, "I cannot remember the last time that Cindy Adams got anything right. She's an idiot, and you can quote me."

On a happier note, Nicole seems to be enjoying the changes her statuesque silhouette is undergoing.

"I'm so happy. I can't ask for anything more except big boobs," Mrs. Keith Urban is quoted as saying (via the London Sun). "I've wanted Marilyn Monroe curves all my life."

TomKat at an Essence event in Los Angeles on Feb. 21

In related news, it doesn't look like Nicole's kids, Bella, 15, and Connor, 13, will be getting a double dose of stepsiblings in the near future. Katie Holmes is shooting down another round of speculation that she's procreated once again with Tom Cruise.

The current cover of OK! asks, "Is She Pregnant?" citing Katie's supposed "10 lb. weight gain" and sudden penchant for "loose-fitting dresses," referring in part to the black-and-white checkered number she wore to a Feb. 21 Essence event, which, despite its pooch-creating design, couldn't quite hide her slim-line figure underneath.

"She has that special glow that only pregnant women have," posits an eyewitness-cum-amateur obstetrician. "I would say there is a strong possibility that she's pregnant."

But 22-month-old Suri doesn't have to worry just yet about sharing her designer wardrobe and pop-up "Dianetics" book.

"She's not pregnant," Holmes' rep tells Us. Still, OK! believes Mrs. Cruise is eager to start baking another sure-to-be "amazing" and "magnificent" bun "so she can buy stylish new maternity clothes."

Brangelina at the Independent Spirit Awards on Feb. 23

Meanwhile, it's been less than a week since Angelina Jolie confirmed, courtesy of a tight-fitting black dress at the Independent Spirit Awards, that she's carrying the fruit of Brad Pitt's loins, but the British tabloids can't seem to agree on how many genetic jackpot winners are gestating in her womb.

"Angelina has been told she is expecting a girl. She's thrilled," a source maintains to the London Sun, pooh-poohing rumors of a double delivery.

The tab also believes Brangelina and brood -- Maddox, 6, Pax, 4, Zahara, 3, and Shiloh, 21 months -- will settle in a chateau in the South of France, a la Johnny Depp and Vanessa Paradis, after their newest ankle-biter arrives.

Of course, those French chateau rumors have been kicking around for a couple of years, so you might want to hold off on that housewarming gift of Brie and baguettes.

The London Daily Mail, for its part, is convinced the dual bundles of joy are a go, quoting a source as saying, "They're having twins, Angelina is healthy, and [Brad is] thrilled that he's going to be a father once again."

Continues the snitch, "Brad's been very quiet about this pregnancy so far but this was the weekend he decided to let the cat out of the bag. He's telling everybody close to him, because he's having to change around his work schedule to get ready for the birth."

The Jolie-Pitts are reportedly spending the next several weeks in Austin, Texas, where the actor is shooting the Terrence Malick drama, "Tree of Life."

Jessica Alba at the Oscars on Feb. 24

And finally, Jessica Alba may still be adjusting to her new center of gravity. In a posting on her MySpace page (we took the liberty of changing her use of all caps), the swelling starlet reveals how relieved she was that she didn't trip up onstage at the Oscars, although she says her footing wasn't quite so secure when the cameras were off.

"I did have a stumble backstage outside of the green room," writes Alba. "[Fiancé] Cash [Warren] caught one arm; the other hit the floor. Luckily, all the photogs were taking pics of Cameron [Diaz], looking gorgeous in pink, I might add."

After the ceremony, the couple skipped the party scene and instead made a beeline for some comfort food and comfort-wear.

"We opted for sweats and In 'n' Out burgers," reveals Jess, who has denied rumors she's expecting twins. "Being preggers kind of takes the fun out of partying until the wee hours. Sleep always sounds so much better these days."
