Pictures: Belly Watch: Boys for Halle and Christina?

See More... Are Halle Berry and Christina Aguilera feeling kind of blue these days? Rumblings from deep inside their bulging bellies are predicting their stork deliveries will be decidedly masculine.

Let's start with Halle, who is expecting her first tot with Canadian model-squeeze Gabriel Aubry. The New York Post rolls the dice in the 50-50 game of gender chance and declares the comely couple's genetic lottery-winning bundle of joy will be a boy.

"She's so excited," a confidante tells the paper. "She says she's never been happier than now, when she's pregnant."

In related womb news, Christina was surrounded by oodles of blue during a baby shower Saturday at her Beverly Hills, Calif., estate, reports People.

The gathering, which is reportedly the first of three planned events for the first-time mom, attracted close friends, family, several drag queens (no, really) and celebrity pals such as Gwen Stefani and Gavin Rossdale, who were greeted with a sign welcoming them to "Christina's Kiddyland Carnival."

Blue and white balloons festooned the party area, and the mag says gifts from Los Angeles baby boutique Bel Bambini followed the color scheme, including a bassinet with blue-hued bedding and blue clothing. There was also a handy item called the Whizz Kid Weeblock, a spongelike device meant to prevent accidental soaking when changing a baby boy.

This latest report on the contents of the makeup-dependent pop princess' womb comes just days after she reportedly picked out $12,000 in pricey products -- all in blue -- at that other de rigueur Los Angeles baby store, Petit Tresor.

Meanwhile, OK! claims Xtina has been rubbing her belly and calling her impending arrival Jordy, after husband Jordan Bratman.

And in a final bit of baby burbling, it may not have quite the same resonance as that whole "no room at the inn" thing, but expectant parents Nicole Richie and Joel Madden are apparently having trouble finding a place to nest.

Us Weekly reports the swelling but still itsy-bitsy starlet and her Good Charlotte front man fiancé were thwarted in their attempts to buy a home in a gated California community because neighbors were (rightfully) worried about an influx of paparazzi.

"Nicole was livid because she loved the house," a spy tells the mag. "She thinks it's a BS reason, but she couldn't fight it."
