Angelina Jolie's closets are crammed with enough black clothing to put both Johnny Cash and Elvira to shame, but it looks like her soon-to-arrive, genetically superior ankle-biters are going to be swaddled in a far lighter shade.

People reports the twins-incubating Oscar winner and Brad Pitt popped into swanky baby boutique Bonpoint in Cannes, France, on Monday to stock up on clothes for their tots.

A store staffer tells the mag the domestic blissed-out duo, who had Shiloh, nearly 2, and Maddox, 6, in tow, purchased "only white, white, white" for the newest members of their brood, which also includes 4-year-old Pax and 3-year-old Zahara.

Since the hue offered no clue about the contents of Jolie's womb, a bold employee reportedly asked her what she's having.

"I don't know yet," a long-black-dress-clad Angelina supposedly responded. "We don't want to know."

Still, rumblings continue that the girls will soon seriously outnumber the boys in the Brangelina household.

FoxNews.com's Roger Friedman says that when he caught up with the Oscar winner at the Cannes Film Festival last week, she told him "there was a line" on the ultrasound showing her "daughters" were going to be fraternal, not identical.

However, based on our intensive two minutes of research, it seems fraternal twins can only be 100 percent identified in-utero if they're a boy and a girl, which means Brad's more glowing, gorgeous half may still be trying to keep part of her pregnancy private.

And who can blame her given the increasingly long lens of the paparazzi, which a few days ago captured Jolie changing her top -- and flashing her own set of impressive twins -- on the balcony of Paul Allen's palatial villa in Saint Jean Cap Ferrat.

Meanwhile, as the world breathlessly counts down to the debut of the future double tabloid toppers, two other members of the Brangelina bunch are experiencing their own adorable version of mom's swelling stomach.

"Our 3-year-old and our 4-year-old keep saying that they have animals in their belly," Jolie told Britain's GMTV last week of Zahara and Pax. "So our daughter keeps saying that she's got little piggies and she has to eat brownies because the piggies need to eat brownies. And our 4-year-old ... says he's got monkeys. So, it's become fun in the house."

Go on, say it, we know you want to ... awwwww.

Nicole shows off her burgeoning belly at the ACM Awards.

In other bun-in-the-oven news, ever since Nicole Kidman confirmed in January that she and Keith Urban were expecting their first child together, amateur obstetricians have unkindly questioned the size of her belly (she's an Amazon, people, which means she probably won't swell up like her more petite peers).

And it turns out the porcelain-visaged actress, who made a point of keeping her hands under her impressively bulbous midsection at the Academy of Country Music Awards on Sunday night, can't even catch a break while working up a sweat.

The Los Angeles Times reports Kidman hit a spinning class on Saturday and Sunday at a Los Angeles gym, where spies say she "worked out hard, kept a good pace, drank a lot of bottled water and used a towel to wipe the sweat off her face several times during both hour long spins."

But, a buttinsky classmate points out, "Nicole tends to keep her head down when she spins which isn't advised because it's bad posture that cuts off your airway and lessens your oxygen intake."

Everyone really is a critic.

Meanwhile, the New York Daily News reports Kidman has chosen famed photographer Patrick Demarchelier to capture her enceinte state, with a source explaining, "But she wants to wait till she looks really pregnant."

Nicole, however, apparently already believes she's plenty far along, telling reporters at the ACM Awards (via People), "We're very excited. We're very pregnant and good."

And finally, are you on pins and bongos needles waiting for the day when Matthew McConaughey unveils the fruit of his laid-back loins?

Yeah, us either, but TMZ.com says the actor and his stork-awaiting squeeze, Camila Alves, have received million-dollar-plus offers from three different outlets (yes, three) for the exclusive rights to publish their baby pics.

Here's predicting at least one shot will show the former Sexiest Man Alive feeling the burn with his small fry strapped securely to his oft-bare chest.
