The thought of Nicollette Sheridan and Michael Bolton procreating sends us to a scary visual place filled with cleavage-thrusting maternity wear and a tiny, mullet-topped bundle of joy gurgling along to "When a Man Loves a Woman."

Nevertheless, there are rumblings the "Desperate Housewives" blonde, 43, and the kitschy crooner, 54, who have been engaged for nearly two years, are in the family way.

An insider told last week's National Enquirer that Sheridan is "absolutely glowing" (we're not quite sure how that differs from her usual shiny and smooth visage) and her purported knocked-up state is "the buzz of the set."

"Nicollette kept asking Felicity [Huffman] and Marcia [Cross] about how the pregnancy would change her appearance," alleged the snitch, "and if it would make her hair thinner."

The baby rumors come just a couple of months after "Desperate" creator Marc Cherry joked that he's forbidden his leading ladies from getting pregnant for the sake of his story line, saying of Sheridan, "I don't think [she] wants to have kids."

But it appears the actress may be more worried about the health of her hair than her lungs.

OK! magazine says it saw her puffing on a couple of cancer sticks during a night out in Los Angeles earlier this week.

Not surprisingly, Sheridan's rep tells the mag the stork rumors are "not true."

Another ABC star denying she's about to join Hollywood's endless poopie diaper parade: Kate Walsh, who insists her focus is firmly on "Private Practice," not starting a family with her TV exec hubby Alex Young, whom she wed in September after a whirlwind seven-month courtship.

"I'm pregnant with triplets now and I feel really good," she cracks to "Extra." "No, I'm not. Right now my baby is 'Private Practice.' She is beautiful and strong, growing every week."

Meanwhile, Victoria Beckham recently touched off baby talk by browsing the luxe wares at ubiquitous Los Angeles baby boutique Petit Tresor, reports OK!

The stringy, stacked mother of three boys, who has repeatedly expressed her desire for a girl (presumably to teach the little one the joys of couture and the evils of carbs), supposedly selected a baby blanket and a stuffed animal in the color pink. She also appeared to be researching a nursery design.

But a rep for Posh, who will soon embark on a world tour with her fellow Spice Girls, tells the mag she's "not pregnant."

Also raising eyebrows with a Petit Tresor stop-by is Matthew McConaughey's bombshell Brazilian squeeze Camila Alves.

The New York Daily News reports she was spied at the store Sunday night checking out baby furniture and picking up a diaper bag.

Sure, she could have easily been shopping for a friend, but that doesn't make the notion of McConaughey attempting to discipline a laid-back, shirt-shunning, exercise-happy ankle-biter any less amusing.
